sound: track kqueue low watermark per-knote for mmaped channels
Use kn->kn_sdata to track the last bs->total value for each knote
attached to an mmaped channel. An event is delivered only when the total
byte counter has advanced by at least c->lw since the last delivery.
After delivery kn_sdata is updated to the current total.
Each knote tracks its own watermark independently, so multiple knotes
attached to the same mmaped channel all receive events correctly.
Non-mmap channels keep the existing level-triggered behavior via
chn_polltrigger().

ibcore: Fix GID sysctl fallback formatting
When a GID table entry is empty or not yet present in the cache,
show_port_gid() falls back to printing a zero GID. Use the existing
GID_PRINT_FMT/GID_PRINT_ARGS helpers instead of Linux's %pI6 format,
which FreeBSD printf treats as a pointer followed by "I6".
This makes empty GID sysctl entries consistently report
0000:0000:0000:0000:0000:0000:0000:0000.

gss_impl.c: Fix a nfsd hang when the kgssapi.ko is loaded, but no gssd
After the conversion to using netlink, the kgssapi had
no way of knowing if the gssd daemon was running.
As such, a boot where the kgssapi is loaded, but the
gssd is not enabled would hang the nfsd for a very
long time. (Many timeouts at 300sec each.)
This patch adds a Null RPC upcall with a 200msec
timeout to check to see if the gssd is running.
If the gssd is not running, the nfsd starts up
(without Kerberos support) with only a 200msec
delay.)
Also, move the svc_svc_nl_create() and svc_reg() calls in gssd.c
to before the daemon() call, so they are guaranteed to have
been done before the nfsd(8) daemon is started by
the rc scripts.

fwip: Fix M_PKTHDR loss in fwip_async_output broadcast path
M_PREPEND in the broadcast branch may call m_prepend(9) which allocates
a new head mbuf and calls m_move_pkthdr(), stripping M_PKTHDR from the
old mbuf.
xfer->mbuf was set before M_PREPEND, so it pointed at the
deheadered old mbuf. bus_dmamap_load_mbuf(9) asserts M_PKTHDR and
panics.
