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.

type for the driver, which will be used for 802.11 drivers.
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.)
* 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.
don't assume that tick is >= 1000; loses badly on alpha (div. by zero)
only try unaligned copies if NetBSD's UNALIGNED_ACCESS symbol is defined.
various misc type size cleanups, mostly short -> int16_t.
