and net.bpf.peers sysctls respectively.
A new structure was added to describe the external (user viewable)
representation of a BPF file; a new entry was added to the bpf_d
structure to store the PID of the calling process; a simple_lock was added
to protect the insert/removal from the net.bpf.peers sysctl handler.
This idea came from FreeBSD (Christian S.J. Peron) but while it is
implemented with sysctl's it differs a bit.
Reviewed by: christos@ and atatat@ (who gave me the tip for the net.bpf.peers
sysctl helper function).
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.

Also add 2 APIs to get a list of available DLTs and use one for them.
BIOCGDLTLIST (struct bpf_dltlist)
BIOCSDLT (u_int)
and bpf_change_type() to take just a pointer to the ifnet, rather than
a pointer to the ifnet and a pointer to a member of the ifnet (the bpf
pointer).
We'll let this ride on the Dec 12 1.5N version bump.
Tree structure:
- sys/arch/sh3: sh3 generic code
As commented, in-chip device drivers are put into sys/arch/sh3/dev.
- sys/arch/evbsh3: sh3 evaluation boards (pure sh3 CPU, no fancy external HW)
- sys/arch/mmeye: Brains mmEye, www.brains.co.jp
MI source code includes couple of #ifdef for sh3-coff support.
(sh3 uses coff or elf)
Needs some more improvements, especialy in sys/arch/sh3/conf/files.sh3,
to compile the tree (due to last minute tree structure change).
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>.
sizeof(struct bpf_hdr). On machines that we currently support that
can use the old definition (which just covers the size of the data in
struct bpf_hdr), use it even though it's a hack. (This was changed
for the 'new architectures' case so as to be fail-safe; BPF may
waste a few bytes of space per captured packet on new architectures,
but now at least it's more likely to work.)
