de3587025a Fix compilation without INET6 and without INET and INET6 after 
offload support was introduced in r284746.

While here also fix the ioctl() handler for IPv4 added in r279819,
which was never compiled in given opt_inet.h was not included.

394e3bd088 Fix CARP when in use in a HyperV environment: 
- Bump link state when stopping or starting the interface;
 - Don't handle SIOCGIFADDR specially, similar to r277103.

This change is based on a previous revision from Andy Zhang
(Microsoft) who did the diagnostic work and many thanks to
them for their help in supporting the HyperV work.

833e8dc5ab Remove struct arpcom. It is unused by most interface types, that allocate 
it, except Ethernet, where it carried ng_ether(4) pointer.
For now carry the pointer in if_l2com directly.

3e5a6bd16d Make some unwise casts. On i386 these casts wind up being safe. Rather 
than disturb the API, go with these casts to shut gcc up.

672ed870a7 IFC @ r253862 
- change the SI_SUB_RUN_SCHEDULER sysinits in hv_utilc and
hv_netvsc_drv_freebsd.c to SI_SUB_KTHREAD_IDLE, since the
former is no longer in FreeBSD.
  The use of these SYSINITs can probably be removed.

cc759c1995 Microsoft have changed their policy on how the hyper-v code will 
be pulled into FreeBSD. From now, FreeBSD will be considered the
upstream repo.

First step: move the drivers away from the contrib area and into
the base system.

A follow-on commit will include the drivers in the amd64 GENERIC kernel.
