Commit 896516e54a added a new NFS mount option
used for Kerberized NFSv4.1/4.2 mounts. It specifies that
AUTH_SYS be used for state maintenance (also called system)
operations. This allows the mount to be done without the
"gssname" option or a valid Kerberos TGT being held by the
user doing the mount (so it can be specified in fstab(5) for
example).

This ensures that *mpp != NULL iff vn_finished_write() should be
called, regardless of the returned error, except for V_NOWAIT.
The only exception that must be maintained is the case where
vn_start_write(V_NOWAIT) is called with the intent of later dropping
other locks and then doing vn_start_write(V_XSLEEP), which needs the mp
value calculated from the non-waitable call above it.
Also note that V_XSLEEP is not supported by vn_start_secondary_write().

The host selector is only required when the user likes to use the same
LPC device IDs as the physical LPC device. This is an uncommon use case.
For that reason, it makes no sense to exit when we don't find the host
selector.

A machine might exist on multiple networks, all of which offer, say, default
routes or name servers. There's no easy way to indicate in the config
that those options are only valid for a single interface.
Now, we can write:
interface "lan0" {
request routers;
require routers;
}
interface "lan1" {
ignore routers;
}
And only take action on default routes offered on lan0.

Pull Request: #693
Rack is capable of fixed rate or dynamic rate pacing. Both of these can get mixed up when
LRO is not available. This is because LRO will hold off waking up the tcp connection to
processing the inbound packets until the pacing timer is up. Without LRO the pacing only
sort-of works. Sometimes we pace correctly, other times not so much.
This set of changes will make it so pacing works properly in the absence of LRO.

if_bridge receives packets via a special interface, if_bridge_input,
rather than by if_input. Thus, netmap's usual hooking of ifnet routines
does not work as expected. Instead, modify bridge_input() to pass
packets directly to netmap when it is enabled. This applies to both
locally delivered packets and forwarded packets.
When a netmap application transmits a packet by writing it to the host
TX ring, the mbuf chain is passed to if_input, which ordinarily points
to ether_input(). However, when transmitting via if_bridge,
bridge_input() needs to see the packet again in order to decide whether
to deliver or forward. Thus, introduce a new protocol flag,
M_BRIDGE_INJECT, which 1) causes the packet to be passed to
bridge_input() again after Ethernet processing, and 2) avoids passing
the packet back to netmap. The source MAC address of the packet is used
to determine the original "receiving" interface.
