- Only active netmap receive queues should be in the RSS lookup table.
- The RSS table should be restored for NIC operation when the last
active netmap queue is switched off, not the first one.
- Support repeated netmap ON/OFF on a subset of the queues. This works
whether the the queues being enabled and disabled are the only ones
active or not. Some kring indexes have to be reset in the driver for
the second case.

For interfaces that do not support SIOCGIFMEDIA (for which there are
quite a few) the only fallback is to query the interface for
if_data->ifi_link_state. While it's possible to get at if_data for an
interface via getifaddrs(3) or sysctl, both are heavy weight mechanisms.
SIOCGIFDATA is a simple ioctl to retrieve this fast with very little
resource use in comparison. This implementation mirrors that of other
similar ioctls in FreeBSD.

Until we can do proper /etc/rc output on both consoles in multicons
boot (or all of them if we ever generalize), report when we are
booting multicons. Also report the primary console. This will be a big
hint why output stops after this line (though some slow USB discovery
still happens after mountroot / init starts).

Report what console the boot loader is telling the kernel to use:
o Dual (Serial Primary)
o Dual (Video Primary)
o Serial
o Video
This allows the user to interrupt the boot and tweak the cosnole, if
needed, in a trivial way. Useful for installs where the default
selected may not be quite what you want, or when you are running a
dual setup and need to toggle over to the other console being primary.
The 'c'/'C' keys will do the cycling through the consoles. Note:
you'll still have to drop into the loader to set details about serial
consoles. And this doesn't change the console the loader is using.

Rather than hard coding ada0 everywhere, use ${dev}. Also, set
dev=vtbd0 since both qemu and bhyve support this. More work
should be done to use labels instead for fstab.
qemu scripts likely need adjustment. And we should also
likely generate byhve scripts too.
The video on PCI heuristic was broken. It was supposed to infer a
video device when the last element of the path was a PCI DEVICE PATH
node. However, the last node in the device path is an END node, so
this heuristic never fired.
This leads, among other things, to bhyve only producing output in the
serial connection once we leave the boot loader. This restores the
dual headed boot on bhyve + UEFI (as we did in 11.2), but will favor
serial in the absence of other config which may be a change from 11.2.

In order to prioritize iSCSI traffic across a network,
DSCP can be used. In order not to rely on "ipfw setdscp"
or in-network reclassification, this adds the dscp value
directly to the portal group (where TCP sessions are accepted).
The incoming iSCSI session is first handled by ctld for any
CHAP authentication and the socket is then handed off to the
in-kernel iscsi driver without modification of the socket
parameters. Simply setting up the socket in ctld is sufficient
to keep sending outgoing iSCSI related traffic with the
configured DSCP value.

using an open_to_lock_owner4 when that lock_owner4 has already
been created by a previous open_to_lock_owner4. This caused the NFS server
to reply NFSERR_INVAL.
For NFSv4.0, this is an error, although the updated NFSv4.0 RFC7530 notes
that the correct error reply is NFSERR_BADSEQID (RFC3530 did not specify
what error to return).
For NFSv4.1, it is not obvious whether or not this is allowed by RFC5661,
but the NFSv4.1 server can handle this case without error.
This patch changes the NFSv4.1 (and NFSv4.2) server to handle multiple
uses of the same lock_owner in open_to_lock_owner so that it now correctly
interoperates with the Linux NFS client.
It also changes the error returned for NFSv4.0 to be NFSERR_BADSEQID.
Thanks go to Bjorn for diagnosing this and testing the patch.
He also provided a program that I could use to reproduce the problem.

_KERNEL and _STANDALONE are different things. They cannot both be true
at the same time. If things that are normally visible only to _KERNEL
are needed for the _STANDALONE environment, you need to also make them
visible to _STANDALONE. Often times, this will be just a subset of the
required things for _KERNEL (eg global variables are but one example).
sys/cdefs.h is included by pretty much everything in both the loader

A received control packet may cause the transmit queue to be flushed, in
which case ng_l2tp_seq_recv_nr() cancels the transmit timeout handler.
The handler checks to see if it was cancelled before doing anything, but
did so before acquiring the node lock, so a small race window could
cause ng_l2tp_seq_rack_timeout() to attempt to flush an empty queue,
ultimately causing a null pointer dereference.
