* .------------------------------------------------------------.
* | Header(4 * sizeof(t_u16)): Standard command response hdr |
* .------------------------------------------------------------.
* | cap_info/Error Return(t_u16): |
* | 0xFFFF(-1): Internal error for association |
* | 0xFFFE(-2): Authentication unhandled message |
* | 0xFFFD(-3): Authentication refused |
* | 0xFFFC(-4): Timeout waiting for AP response |
* | 0xFFFB(-5): Internal error for authentication |
* .------------------------------------------------------------.
* | status_code(t_u16): |
* | If cap_info is -1: |
* | An internal firmware failure prevented the |
* | command from being processed. The status code |
* | is 6 if associate response parameter invlaid, |
* | 1 otherwise. |
* | |
* | If cap_info is -2: |
* | An authentication frame was received but was |
* | not handled by the firmware. IEEE Status code |
* | for the failure is returned. |
* | |
* | If cap_info is -3: |
* | An authentication frame was received and the |
* | status_code is the IEEE Status reported in the |
* | response. |
* | |
* | If cap_info is -4: |
* | (1) Association response timeout |
* | (2) Authentication response timeout |
* | |
* | If cap_info is -5: |
* | An internal firmware failure prevented the |
* | command from being processed. The status code |
* | is 6 if authentication parameter invlaid, |
* | 1 otherwise. |
* .------------------------------------------------------------.
* | a_id(t_u16): 0xFFFF |
* .------------------------------------------------------------.
*
*
* For cases where an association response was received, the IEEE
* standard association response frame is returned:
*
* .------------------------------------------------------------.
* | Header(4 * sizeof(t_u16)): Standard command response hdr |
* .------------------------------------------------------------.
* | cap_info(t_u16): IEEE Capability |
* .------------------------------------------------------------.
* | status_code(t_u16): IEEE Status Code |
* .------------------------------------------------------------.
* | a_id(t_u16): IEEE Association ID |
* .------------------------------------------------------------.
* | IEEE IEs(variable): Any received IEs comprising the |
* | remaining portion of a received |
* | association response frame. |
* .------------------------------------------------------------.
*
* For simplistic handling, the status_code field can be used to determine
* an association success (0) or failure (non-zero).
