Remove net.link.ether.inet.useloopback sysctl tunable. It was always on by
default from the very beginning. It was placed in wrong namespace
net.link.ether, originally it had been at another wrong namespace. It was
incorrectly documented at incorrect manual page arp(8). Since new-ARP commit,
the tunable have been consulted only on route addition, and ignored on route
deletion. Behaviour of a system with tunable turned off is not fully correct,
and has no advantages comparing to normal behavior.

Comment out IA32_MISC_ENABLE MSR access - this doesn't exist on AMD.
Need to sort out how arch-specific MSRs will be handled.

Merge from head

Add m_clrprotoflags() to clear protocol specific mbuf flags at up and
downwards layer crossings.

Consistently use it within IP, IPv6 and ethernet protocols.

Migrate structs arpstat, icmpstat, mrtstat, pimstat and udpstat to PCPU
counters.

Catch up with r238990. LLE_DELETED does not clobber everything else in
la_flags since said revision.

Merge fresh head.

Rate limit the number of remotely triggered ARP log messages
to 1 log message per second.

Add const qualifier to the dst parameter of the ifnet if_output method.

Fix couple of mbuf leaks in incoming ARP processing.

Fix problem in r238990. The LLE_LINKED flag should be tested prior to
entering llentry_free(), and in case if we lose the race, we should simply
perform LLE_FREE_LOCKED(). Otherwise, if the race is lost by the thread
performing arptimer(), it will remove two references from the lle instead
of one.
