| * On 2004-02-25, a FreeBSD checkin to sys/net/bpf.h was made that |

| * mapping, so it probably supports capturing on the pfsync device |
| * but not saving the captured data to a pcap file. |
| * |
| * OpenBSD, from which pf came, however, uses 18 for DLT_PFSYNC; |
| * their libpcap does no DLT_ <-> LINKTYPE_ mapping, so it would |
| * use 18 in pcap files as well. |
| * |
| * NetBSD and DragonFly BSD also use 18 for DLT_PFSYNC; their |
| * libpcaps do DLT_ <-> LINKTYPE_ mapping, and neither has an entry |
| * for DLT_PFSYNC, so it might not be able to write out dump files |
| * with 18 as the link-layer header type. (Earlier versions might |
| * not have done mapping, in which case they'd work the same way |
| * OpenBSD does.) |
| * |
| * Mac OS X defines it as 18, but doesn't appear to use it as of |
| * Mac OS X 10.7.3. Its libpcap does DLT_ <-> LINKTYPE_ mapping. |

| * except for FreeBSD; anybody who wants to compile, on FreeBSD, code |
| * that uses DLT_HHDLC is out of luck. |
| * |
| * We'll define LINKTYPE_PFSYNC as 18, *even on FreeBSD*, and map |
| * it, so that savefiles won't use 121 for PFSYNC - they'll all |
| * use 18. Code that uses pcap_datalink() to determine the link-layer |
| * header type of a savefile won't, when built and run on FreeBSD, |
