cxgbe tom: Enable ULP_MODE_TCPDDP on demand
Most ULP modes in cxgbe's TOE are enabled on the fly when a protocol
is needed (e.g. ULP_MODE_ISCSI is enabled by cxgbei when offloading a
connection using iSCSI, and ULP_MODE_TLS is enabled when RX TLS keys
are programmed for a TOE connection). The one exception to this is
ULP_MODE_TCPDDP.
Currently the cxgbe driver enables ULP_MODE_TCPDDP when a TOE
connection is first created. However, since DDP connections cannot be
converted to other connection types, this requires some special
handling in the driver. For example, iSCSI daemons use the SO_NO_DDP
socket option to ensure TOE connections use ULP_MODE_NONE so they can
be converted to ULP_MODE_ISCSI. Similarly, using TLS receive offload
(ULP_MODE_TLS) requires disabling TCP DDP for new connections by
default.
This commit changes cxgbe to instead switch a connection from
ULP_MODE_NONE to ULP_MODE_TCPDDP when a connection first attempts to
use TCP DDP via aio_read(2). This permits connections to always start
as ULP_MODE_NONE and switch to a protocol-specific mode as needed.

Previously this was only limited on T6 cards to support switching from

Don't assert mg_initialized due to device addition race
During device removal stress tests, we noticed that we were tripping
the assertion that mg_initialized was true. After investigation, it was
determined that the mg in question was the embedded log metaslab
group for a newly added vdev; the normal mg had been initialized (by
metaslab_sync_reassess, via vdev_sync_done). However, because the spa
config alloc lock is not held as writer across both calls to
metaslab_sync_reassess, it is possible for an allocation to happen
between the two metaslab_groups being initialized. Because the metaslab
code doesn't check the group in question, just the vdev's main mg, it
is possible to get past the initial check in vdev_allocatable and
later fail due to the assertion.
We simply remove the assertions. We could also consider locking the
ALLOC lock around the reassess calls in vdev_sync_done, but that risks
deadlocks. We could check the actual target mg in vdev_allocatable,
but that risks racing with a passivation that comes in after that
check but before the assertion. We still won't be able to actually
allocate from the metaslab group if no metaslabs are ready, so this

to them. (E.g. when rejecting a packet, or when gathering up packets
for reassembly).
If the hook returns PFIL_PASS the mbuf must still be present. Assert
this in pfil_mem_common() and ensure that ipfilter follows this
convention. pf and ipfw already did.
Similarly, if the hook returns PFIL_DROPPED or PFIL_CONSUMED the mbuf
must have been freed (or now be owned by the firewall for further
processing, like packet scheduling or reassembly).
This allows us to remove a few extraneous NULL checks.
The RFC6675 pipe calculation (sack.revised, enabled
by default since D28702), uses outdated information,
while the previous default calculated it correctly
with up-to-date information from the incoming ACK.
This difference can become as large as the receive
window (not the congestion window previously),
potentially triggering a massive burst of new packets.

vtnet: Adjust for ethernet alignment.
If the header that we add to the packet's size is 0 % 4 and we're
strictly aligning, then we need to adjust where we store the header so
the packet that follows will have it's struct ip header properly
aligned. We do this on allocation (and when we check the length of the
mbufs in the lro_nomrg case). We can't just adjust the clustersz in the
softc, because it's also used to allocate the mbufs and it needs to be
the proper size for that. Since we otherwise use the size of the mbuf
(or sometimes the smaller size of the received packet) to compute how
much we can buffer, this ensures no overflows. The 2 byte adjustment
also does not affect how many packets we can receive in the lro_nomrg
case.

release.sh: Add -jN to `make release`
The `make release` command now creates VM and cloudware images (if
enabled) in addition to disk images; this results in a very large
number of 'make installworld' commands running sequentially. Adding
-jN should speed this up significantly.

snd_hdspe(4): Per device sysctl for period.
Let the user choose a period (interrupt cadence in samples), in the
official RME drivers this setting is available as "Buffer Size".
Override the period propagated through blocksize by pcm channel latency
settings (see sound(4)), since these are unreliable and differ between
playback and recording channels.

kboot: update copyright on these files.
host_syscalls.c: I've written, so put Netflix copyright on. It's
possible in the confusion that Nathan wrote the host_gettimeofday
implementation.
syscall_nr: These files likely can't enjoy copyright protection since
they are just facts (the per-arch Linux system calls), so add a note
they are in the public domain.
