+*  delimiters  (in)  Set of delimiter characters.
+*  tokdelim    (out) Character that delimits the returned token. (May

+ * Design Notes:
+ * BCM_MWBMAP_USE_CNTSETBITS trades CPU for memory. A runtime count of how many

+ * array indexed access and 3 arithmetic operations. When not defined, a runtime
+ * count of set bits state is maintained. Upto 32 Bytes per 1024 IDs is needed.
+ * In a 4K max ID allocator, up to 128Bytes are hence used per instantiation.
+ * In a memory limited system e.g. dongle builds, a CPU for memory tradeoff may
+ * be used by defining BCM_MWBMAP_USE_CNTSETBITS.
+ *
+ * Note: wd_bitmap[] is statically declared and is not ROM friendly ... array
+ * size is fixed. No intention to support larger than 4K indice allocation. ID
+ * allocators for ranges smaller than 4K will have a wastage of only 12Bytes
+ * with savings in not having to use an indirect access, had it been dynamically
+ * allocated.

+ * [<band> 'g'] <channel> ['/'<bandwidth> [<ctl-sideband>]['/'<1st80channel>'-'<2nd80channel>]]
+ *
+ * <band>:
+ *      (optional) 2, 3, 4, 5 for 2.4GHz, 3GHz, 4GHz, and 5GHz respectively.
+ *      Default value is 2g if channel <= 14, otherwise 5g.
+ * <channel>:
+ *      channel number of the 5MHz, 10MHz, 20MHz channel,
+ *      or primary channel of 40MHz, 80MHz, 160MHz, or 80+80MHz channel.
+ * <bandwidth>:
+ *      (optional) 5, 10, 20, 40, 80, 160, or 80+80. Default value is 20.
+ * <primary-sideband>:
+ *      (only for 2.4GHz band 40MHz) U for upper sideband primary, L for lower.
+ *
+ *      For 2.4GHz band 40MHz channels, the same primary channel may be the
+ *      upper sideband for one 40MHz channel, and the lower sideband for an

+ *
+ *      For 40MHz in the 5GHz band and all channel bandwidths greater than
+ *      40MHz, the U/L specificaion is not allowed since the channels are
+ *      non-overlapping and the primary sub-band is derived from its
+ *      position in the wide bandwidth channel.
+ *
+ * <1st80Channel>:
+ * <2nd80Channel>:
+ *      Required for 80+80, otherwise not allowed.
+ *      Specifies the center channel of the first and second 80MHz band.
+ *
+ * In its simplest form, it is a 20MHz channel number, with the implied band
+ * of 2.4GHz if channel number <= 14, and 5GHz otherwise.
+ *
+ * To allow for backward compatibility with scripts, the old form for
+ * 40MHz channels is also allowed: <channel><ctl-sideband>
+ *
+ * <channel>:
+ *	primary channel of 40MHz, channel <= 14 is 2GHz, otherwise 5GHz
+ * <ctl-sideband>:
+ * 	"U" for upper, "L" for lower (or lower case "u" "l")

+ *
+ * There are two types of Job, that needs to be assigned to

+ * 1) Rx Packet Processing - napi_cpu
+ * 2) Completion Processiong (Tx, RX) - compl_cpu
+ *
+ * To begin with both napi_cpu and compl_cpu are on CPU0. Whenever a CPU goes
+ * on-line/off-line the CPU candidacy algorithm is triggerd. The candidacy
+ * algo tries to pickup the first available non boot CPU (CPU0) for napi_cpu.
+ * If there are more processors free, it assigns one to compl_cpu.
+ * It also tries to ensure that both napi_cpu and compl_cpu are not on the same
+ * CPU, as much as possible.
+ *
+ * By design, both Tx and Rx completion jobs are run on the same CPU core, as it
+ * would allow Tx completion skb's to be released into a local free pool from
+ * which the rx buffer posts could have been serviced. it is important to note
+ * that a Tx packet may not have a large enough buffer for rx posting.

+ *  BCMPCIE_H2D_COMMON_MSGRINGS = 2, i.e. 2 H2D common rings,
+ *  BCMPCIE_COMMON_MSGRINGS     = 5, i.e. include 3 D2H common rings.
+ *
+ *  H2D Control  Submit   RingId = 0        FlowId = 0 reserved never allocated
+ *  H2D RxPost   Submit   RingId = 1        FlowId = 1 reserved never allocated
+ *
+ *  D2H Control  Complete RingId = 2
+ *  D2H Transmit Complete RingId = 3
+ *  D2H Receive  Complete RingId = 4
+ *
+ *  H2D TxPost   FLOWRING RingId = 5         FlowId = 2     (1st flowring)
+ *  H2D TxPost   FLOWRING RingId = 6         FlowId = 3     (2nd flowring)
+ *  H2D TxPost   FLOWRING RingId = 5 + (N-1) FlowId = (N-1) (Nth flowring)
+ *
+ * When TxPost FlowId(s) are allocated, the FlowIds [0..FLOWID_RESERVED) are
+ * unused, where FLOWID_RESERVED is BCMPCIE_H2D_COMMON_MSGRINGS.
+ *
+ * Example: when a system supports 4 bc/mc and 128 uc flowrings, with
+ * BCMPCIE_H2D_COMMON_MSGRINGS = 2, and BCMPCIE_H2D_COMMON_MSGRINGS = 5, and the
+ * FlowId values would be in the range [2..133] and the corresponding
+ * RingId values would be in the range [5..136].
+ *
+ * The flowId allocator, may chose to, allocate Flowids:
+ *   bc/mc (per virtual interface) in one consecutive range [2..(2+VIFS))
+ *   X# of uc flowids in consecutive ranges (per station Id), where X is the
+ *   packet's access category (e.g. 4 uc flowids per station).
+ *
+ * CAUTION:
+ * When DMA indices array feature is used, RingId=5, corresponding to the 0th
+ * FLOWRING, will actually use the FlowId as index into the H2D DMA index,
+ * since the FlowId truly represents the index in the H2D DMA indices array.
+ *
+ * Likewise, in the D2H direction, the RingId - BCMPCIE_H2D_COMMON_MSGRINGS,
+ * will represent the index in the D2H DMA indices array.

+ * Each DMA-able buffer may be allocated independently, or may be carved out
+ * of a single large contiguous region that is registered with the protocol
+ * layer into flowrings_dma_buf. On a 64bit platform, this contiguous region
+ * may not span 0x00000000FFFFFFFF (avoid dongle side 64bit ptr arithmetic).
+ *
+ * No flowring pool action is performed in dhd_prot_attach(), as the number
+ * of h2d rings is not yet known.
+ *
+ * In dhd_prot_init(), the dongle advertized number of h2d rings is used to
+ * determine the number of flowrings required, and a pool of msgbuf_rings are
+ * allocated and a DMA-able buffer (carved or allocated) is attached.
+ * See: dhd_prot_flowrings_pool_attach()
+ *
+ * A flowring msgbuf_ring object may be fetched from this pool during flowring
+ * creation, using the flowid. Likewise, flowrings may be freed back into the
+ * pool on flowring deletion.
+ * See: dhd_prot_flowrings_pool_fetch(), dhd_prot_flowrings_pool_release()
+ *
+ * In dhd_prot_detach(), the flowring pool is detached. The DMA-able buffers
+ * are detached (returned back to the carved region or freed), and the pool of
+ * msgbuf_ring and any objects allocated against it are freed.
+ * See: dhd_prot_flowrings_pool_detach()
+ *
+ * In dhd_prot_reset(), the flowring pool is simply reset by returning it to a
+ * state as-if upon an attach. All DMA-able buffers are retained.
+ * Following a dhd_prot_reset(), in a subsequent dhd_prot_init(), the flowring
+ * pool attach will notice that the pool persists and continue to use it. This
+ * will avoid the case of a fragmented DMA-able region.

+ * Memory pools library, Public interface
+ *
+ * API Overview
+ *
+ * This package provides a memory allocation subsystem based on pools of
+ * homogenous objects.
+ *
+ * Instrumentation is available for reporting memory utilization both
+ * on a per-data-structure basis and system wide.
+ *
+ * There are two main types defined in this API.
+ *
+ *    pool manager: A singleton object that acts as a factory for
+ *                  pool allocators. It also is used for global
+ *                  instrumentation, such as reporting all blocks
+ *                  in use across all data structures. The pool manager
+ *                  creates and provides individual memory pools
+ *                  upon request to application code.
+ *
+ *    memory pool:  An object for allocating homogenous memory blocks.
+ *
+ * Global identifiers in this module use the following prefixes:
+ *    bcm_mpm_*     Memory pool manager
+ *    bcm_mp_*      Memory pool
+ *
+ * There are two main types of memory pools:
+ *
+ *    prealloc: The contiguous memory block of objects can either be supplied
+ *              by the client or malloc'ed by the memory manager. The objects are
+ *              allocated out of a block of memory and freed back to the block.
+ *
+ *    heap:     The memory pool allocator uses the heap (malloc/free) for memory.
+ *              In this case, the pool allocator is just providing statistics
+ *              and instrumentation on top of the heap, without modifying the heap
+ *              allocation implementation.

+ *
+ * bcm_ring.h : Ring context abstraction
+ *
+ * The ring context tracks the WRITE and READ indices where elements may be
+ * produced and consumed respectively. All elements in the ring need to be
+ * fixed size.
+ *
+ * NOTE: A ring of size N, may only hold N-1 elements.
+ *
+ * +----------------------------------------------------------------------------
+ *
+ * API Notes:
+ *
+ * Ring manipulation API allows for:
+ *  Pending operations: Often before some work can be completed, it may be
+ *  desired that several resources are available, e.g. space for production in
+ *  a ring. Approaches such as, #1) reserve resources one by one and return them
+ *  if another required resource is not available, or #2) employ a two pass
+ *  algorithm of first testing whether all resources are available, have a
+ *  an impact on performance critical code. The approach taken here is more akin
+ *  to approach #2, where a test for resource availability essentially also
+ *  provides the index for production in an un-committed state.
+ *  The same approach is taken for the consumer side.
+ *
+ *  - Pending production: Fetch the next index where a ring element may be
+ *    produced. The caller may not commit the WRITE of the element.
+ *  - Pending consumption: Fetch the next index where a ring element may be
+ *    consumed. The caller may not commut the READ of the element.
+ *
+ *  Producer side API:
+ *  - bcm_ring_is_full  : Test whether ring is full
+ *  - bcm_ring_prod     : Fetch index where an element may be produced (commit)
+ *  - bcm_ring_prod_pend: Fetch index where an element may be produced (pending)
+ *  - bcm_ring_prod_done: Commit a previous pending produce fetch
+ *  - bcm_ring_prod_avail: Fetch total number free slots eligible for production
+ *
+ * Consumer side API:
+ *  - bcm_ring_is_empty : Test whether ring is empty
+ *  - bcm_ring_cons     : Fetch index where an element may be consumed (commit)
+ *  - bcm_ring_cons_pend: Fetch index where an element may be consumed (pending)
+ *  - bcm_ring_cons_done: Commit a previous pending consume fetch
+ *  - bcm_ring_cons_avail: Fetch total number elements eligible for consumption
+ *
+ *  - bcm_ring_sync_read: Sync read offset in peer ring, from local ring
+ *  - bcm_ring_sync_write: Sync write offset in peer ring, from local ring
+ *
+ * +----------------------------------------------------------------------------
+ *
+ * Design Notes:
+ * Following items are not tracked in a ring context (design decision)
+ *  - width of a ring element.
+ *  - depth of the ring.
+ *  - base of the buffer, where the elements are stored.
+ *  - count of number of free slots in the ring
+ *
+ * Implementation Notes:
+ *  - When BCM_RING_DEBUG is enabled, need explicit bcm_ring_init().
+ *  - BCM_RING_EMPTY and BCM_RING_FULL are (-1)
+ *
+ * +----------------------------------------------------------------------------
+ *
+ * Usage Notes:
+ * An application may incarnate a ring of some fixed sized elements, by defining
+ *  - a ring data buffer to store the ring elements.
+ *  - depth of the ring (max number of elements managed by ring context).
+ *    Preferrably, depth may be represented as a constant.
+ *  - width of a ring element: to be used in pointer arithmetic with the ring's
+ *    data buffer base and an index to fetch the ring element.
+ *
+ * Use bcm_workq_t to instantiate a pair of workq constructs, one for the
+ * producer and the other for the consumer, both pointing to the same circular
+ * buffer. The producer may operate on it's own local workq and flush the write
+ * index to the consumer. Likewise the consumer may use its local workq and
+ * flush the read index to the producer. This way we do not repeatedly access
+ * the peer's context. The two peers may reside on different CPU cores with a
+ * private L1 data cache.

+ * if this tag is disabled.
+ *
+ * To support easy usage of existing debugging (e.g. msglevel) via macro re-definition there are
+ * two variants of these macros to help.
+ *
+ * First there are the CAST versions.  The event_log function normally logs uint32 values or else
+ * they have to be cast to uint32.  The CAST versions blindly cast for you so you don't have to edit
+ * any existing code.
+ *
+ * Second there are the PAREN_ARGS versions.  These expect the logging format string and arguments
+ * to be enclosed in parentheses.  This allows us to make the following mapping of an existing
+ * msglevel macro:
+ *  #define WL_ERROR(args)   EVENT_LOG_CAST_PAREN_ARGS(EVENT_LOG_TAG_WL_ERROR, args)
+ *
+ * The versions of the macros without FAST or COMPACT in their name are just synonyms for the
+ * COMPACT versions.
+ *
+ * You should use the COMPACT macro (or its synonym) in cases where there is some preceding logic
+ * that prevents the execution of the macro, e.g. WL_ERROR by definition rarely gets executed.
+ * Use the FAST macro in performance sensitive paths. The key concept here is that you should be
+ * assuming that your macro usage is compiled into ROM and can't be changed ... so choose wisely.
