* Resize some types. In particular, bfs_seqno can be uint16_t for now. Previous work would assign the unassigned seqno a value of -1, which I obviously can't do here. * Remove bfs_pktdur. It was in the original code but nothing so far uses it. This gets ath_buf down (on my i386 system) to 292 bytes from 300 bytes. I'd rather it be much, much smaller.
