Modified files:
sys/net bpf.h
Log:
Don't attempt to optimize the space allocated for bpf headers if
sizeof(struct bpf_hdr) > 20. 20 is normal on 32-bit systems with
32-bit alignment, but we still assume that the last 2 bytes of the
struct are unnecessary padding on such systems. On systems with
64-bit longs, struct timeval is bloated to 16 bytes, so bpf headers
certainly don't fit in 18 bytes.
