2fbf6cf055 MFS: Make struct arpcom the first entry in softc. (There are at least
two functions in sys/net/if.c that assume that softc starts with arpcom.)
This makes setting of ethernet address via ifconfig(8) work as expected.

efd8e7c9b6 The last argument to mtx_init() should be MTX_DEF, not 0. This is not a
functional change since MTX_DEF happens to be defined as 0.

f6a1906569 Lower the maximum ACK timeout for GRE packets from 10 to 1 second.
In practice it seems that in situations of high packet loss the ACK
timeout seems to hit this maximum (perhaps inappropriately, but the
estimation algorithm is not perfect, so apparently it happens). In
any case, 10 seconds is way too high a value so lower to 1 second.

a557af222b Introduce a MAC label reference in 'struct inpcb', which caches
the   MAC label referenced from 'struct socket' in the IPv4 and
IPv6-based protocols.  This permits MAC labels to be checked during
network delivery operations without dereferencing inp->inp_socket
to get to so->so_label, which will eventually avoid our having to
grab the socket lock during delivery at the network layer.

This change introduces 'struct inpcb' as a labeled object to the
MAC Framework, along with the normal circus of entry points:
initialization, creation from socket, destruction, as well as a
delivery access control check.

For most policies, the inpcb label will simply be a cache of the
socket label, so a new protocol switch method is introduced,
pr_sosetlabel() to notify protocols that the socket layer label
has been updated so that the cache can be updated while holding
appropriate locks.  Most protocols implement this using
pru_sosetlabel_null(), but IPv4/IPv6 protocols using inpcbs use
the the worker function in_pcbsosetlabel(), which calls into the
MAC Framework to perform a cache update.

Biba, LOMAC, and MLS implement these entry points, as do the stub
policy, and test policy.

adcdb48eb5 Replace the lock-less algorithm for the free item list with a more
conservative lock. The problem with the lock-less algorithm is that
it suffers from the ABA problem. Running an application with funnels
a couple of 100kpkts/s through the netgraph system on a dual CPU system
with MPSAFE drivers will panic almost immediatly with the old algorithm.

It may be possible to eliminate the contention between threads that insert
free items into the list and those that get free items by using the
Michael/Scott queue algorithm that has two locks.

9bf40ede4a Replace the if_name and if_unit members of struct ifnet with new members
if_xname, if_dname, and if_dunit. if_xname is the name of the interface

This change paves the way for interface renaming and enhanced pseudo

ed692400eb I don't know from where the notion that device driver should or
even could call VOP_REVOKE() on vnodes associated with its dev_t's
has originated, but it stops right here.

If there are things people belive destroy_dev() needs to learn how to
do, please tell me about it, preferably with a reproducible test case.

Include <sys/uio.h> in bluetooth code rather than rely on <sys/vnode.h>
to do so.

The fact that some of the USB code needs to include <sys/vnode.h>
still disturbs me greatly, but I do not have time to chase that.
