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.

caa3136039 Uh, ya, sure this almost compiled for __bsdi__. NOT!
Note that __bsdi__s_/_i_/_os_/__ has moved this file to dev/ic/ and
has completely removed the non-compiling function from pdq_ifsubr.c and
has completely removed this function and placed it into netinet/if_ether.c
(if, in fact, it wasn't there the whole time).  I was tempted to simply
remove this __bsdi__only__ function.

The function is arp_ifinit().

46783fb897 Remove NBPF conditionality of bpf calls in most of our network drivers.
This means that we will not have to have a bpf and a non-bpf version
of our driver modules.

This does not open any security hole, because the bpf core isn't loadable

The drivers left unchanged are the "cross platform" drivers where the respective
maintainers are urged to DTRT, whatever that may be.

Add a couple of missing FreeBSD tags.

1d5e9e2255 Make INET a proper option.
This will not make any of object files that LINT create change; there
might be differences with INET disabled, but hardly anything compiled
before without INET anyway.  Now the 'obvious' things will give a
proper error if compiled without inet - ipx_ip, ipfw, tcp_debug.  The
only thing that _should_ work (but can't be made to compile reasonably
easily) is sppp :-(

This commit move struct arpcom from <netinet/if_ether.h> to
<net/if_arp.h>.

51a534883a Don't include <sys/ioctl.h> in the kernel. Stage 2: include
<sys/sockio.h> instead of <sys/ioctl.h> in network files.

87a6a0f90a Catch up with the moving target: merge the change from rev 1.19 of the
now dead sys/pci/if_pdq.c which has been committed about by the same
time i made my tests with Matt's code.

LINT should compile now again.

Well, that's a clear case where ``CVS writer locks'' would certainly
(not) have helped. :-]

e4107dcf00 This mega-merge brings Matt Thomas' 960801 FDDI driver (almost) up
to -current.

Thanks goes to Ulrike Nitzsche <ulrike@ifw-dresden.de> for giving me
a chance to test this.  Only the PCI driver is tested though.

One final patch will follow in a separate commit.  This is so that
everything up to here can be dragged into 2.2, if we decide so.

b05ee6a563 Finally import the 960801 of Matt Thomas' DEC FDDI driver. I'm
importing it onto a vendor branch first, in the hope that this will
make future maintenance easier.

The conflicts are (hopefully) unimportant.  More commits that actually
bring this into the source tree will follow.
