particule device. In doing this, make a new the bpf_stat structure with
members that are u_long rather than u_int, matching the counters in the bpf_d.
the original bpf_stat is now bpf_stat_old and so to the original ioctl
is preserved as BIOCGSTATSOLD.
Fix the behaviour of BIOCIMMEDIATE (fix from LBL BPF code via FreeBSD.)
In bpf_mtap(), optimise the calling of bpf_filter() and catchpacket()
based on whether or not the entire packet is in one mbuf (based on
similar change FreeBSD but fixes BIOC*SEESENT issue with that.)
Copy the implementation of BIOCSSEESENT, BIOCGSEESENT by FreeBSD.

the "header already complete" flag. This allows BPF writers to spoof
layer 2 source addresses (providing the layer 2 in use supports it) in
applications where this is necessary. From Greg Smith <greg@nas.nasa.gov>.
* grok FIONBIO, FIOASYNC, and TIOC{G,S}PGRP
* add BIOC{G,S}RSIG; get/set the signal to be delivered
to the process or process group upon packet reception.
Defaults to SIGIO.
