9967cafc49 Correct mbuf packet header propagation. Previously, packet headers
were sometimes propagated using M_COPY_PKTHDR which actually did
something between a "move" and a  "copy" operation.  This is replaced
by M_MOVE_PKTHDR (which copies the pkthdr contents and "removes" it
from the source mbuf) and m_dup_pkthdr which copies the packet
header contents including any m_tag chain.  This corrects numerous
problems whereby mbuf tags could be lost during packet manipulations.

These changes also introduce arguments to m_tag_copy and m_tag_copy_chain
to specify if the tag copy work should potentially block.  This
introduces an incompatibility with openbsd which we may want to revisit.

Note that move/dup of packet headers does not handle target mbufs
that have a cluster bound to them.  We may want to support this;
for now we watch for it with an assert.

Finally, M_COPYFLAGS was updated to include M_FIRSTFRAG|M_LASTFRAG.

673d91916d network interface driver changes:
o don't strip the Ethernet header from inbound packets; pass packets
  up the stack intact (required significant changes to some drivers)
o reference common definitions in net/ethernet.h (e.g. ETHER_ALIGN)
o track ether_ifattach/ether_ifdetach API changes
o track bpf changes (use BPF_TAP and BPF_MTAP)
o track vlan changes (ifnet capabilities, revised processing scheme, etc.)
o use if_input to pass packets "up"
o call ether_ioctl for default handling of ioctls

6d3ffec0e5 Make this build on 4.x machines again (building a -current kernel on a
-stable machine via the old-school methods):

Use __FreeBSD_version in preference to __FreeBSD__ >= N where possible.
Define a single variable mythread which is set to curproc or curthread
depending on the OS version (with a comment saying it is a white lie on
4.x since it really is a proc).

NB: __FreeBSD__ is the OS level of the host machine, not the target,
and should never be used, if possible, as __FreeBSD__ >= N.

44731cab3b Change the suser() API to take advantage of td_ucred as well as do a
general cleanup of the API.  The entire API now consists of two functions
similar to the pre-KSE API.  The suser() function takes a thread pointer
as its only argument.  The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0.  The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

This is functionally equivalent to teh previousl -current except

419d8080a4 Currently, each wireless networking driver has it's own control program
despite the fact that most people want to set exactly the same settings
regardless of which card they have.  It has been repeatidly suggested
that this configuration should be done via ifconfig.  This patch
implements the required functionality in ifconfig and add support to the
wi and an drivers.  It also provides partial, untested support for the
awi driver.

df5e198723 Lock down the network interface queues. The queue mutex must be obtained
before adding/removing packets from the queue.  Also, the if_obytes and
if_omcasts fields should only be manipulated under protection of the mutex.

IF_ENQUEUE, IF_PREPEND, and IF_DEQUEUE perform all necessary locking on
the queue.  An IF_LOCK macro is provided, as well as the old (mutex-less)
versions of the macros in the form _IF_ENQUEUE, _IF_QFULL, for code which
needs them, but their use is discouraged.

Two new macros are introduced: IF_DRAIN() to drain a queue, and IF_HANDOFF,
which takes care of locking/enqueue, and also statistics updating/start
if necessary.

302ffdfd98 awi needs to access memory with 8bit,
but pccardd apparently maps memory with MDF_16BITS flag.
So memory mapped access is disabled and use IO port instead for now.

2e2de7f23f Move code to handle BPF and bridging for incoming Ethernet packets out
of the individual drivers and into the common routine ether_input().
Also, remove the (incomplete) hack for matching ethernet headers
in the ip_fw code.

The good news: net result of 1016 lines removed, and this should make
bridging now work with *all* Ethernet drivers.

The bad news: it's nearly impossible to test every driver, especially
for bridging, and I was unable to get much testing help on the mailing
lists.
