06824d2c88 sfxge: prefetch txq->common if TxQ is started only
Transmit may be called when TxQ is not started yet (i.e. txq->common is
invalid). TxQ state is checked below when mbuf is processed and dropped
if TxQ is not started.

93c3ad10f1 Fix minor fallout from sysctl strings being nulterminated now. The dmesg
code can read the buffer via sysctl or from a core file.  In the core file
case there will be no nulterm, and the code copes with that, but now in the
sysctl case there is a nulterm (there didn't used to be).  The least
disruptive way to restore the old behavior (and eliminate a spurious '\000'
at the end of the output) is to remove the nulterm (by decrementing the
buffer length) in the sysctl case.

f62fbd30cb Trivial change / forced-commit to document prior change that slipped in
without a commit message...

Use sbuf_new() + SYSCTL_OUT() instead of wiring the userland buffer and
using sbuf_new_for_sysctl().  The preallocated 256 byte buffer is always
going to be big enough to hold these results, and this should be more
efficient than wiring the old buffer.

8d5628fdb8 Update an sbuf assertion to allow for the new SBUF_INCLUDENUL flag. If
INCLUDENUL is set and sbuf_finish() has been called, the length has been
incremented to count the nulterm byte, and in that case current length is
allowed to be equal to buffer size, otherwise it must be less than.

Add a predicate macro to test for SBUF_INCLUDENUL, and use it in tests, to
be consistant with the style in the rest of this file.

d2925cccc1 Introduce a cap_ioctl_t used for the 'cmds' arguments to cap_ioctls_limit()
and cap_ioctls_get().  On FreeBSD, these are 'unsigned long', but on Linux,
ioctl(2) takes an 'int', making mild abstraction desirable.

ad7ea69dce Convert PTE eviction lock from an RW lock to a RM lock. It is held for
writing approximately never (< 0.00000001% under heavy VM load, and it can

c077e6287f Report ARAT (APIC-Timer-always-running) feature for virtual CPU.
This makes FreeBSD guest to not avoid using LAPIC timer, preferring HPET
due to worries about non-existing for virtual CPUs deep sleep states.

Benchmarks of usleep(1) on guest and host show such extra latencies:
 - 51us for virtual HPET,
 - 22us for virtual LAPIC timer,
 - 22us for host HPET and
 - 3us for host LAPIC timer.

3bd3e39e1a Start fleshing out some MAC address helper functions.
A lot of these embedded boards don't have a unique MAC address per
device stored somewhere unique - sometimes they'll have one MAC
for both arge NICs; someties they'll have one MAC for both arge NICs
/and/ the ath NICs.  In these instances, we need to derive device
specific MAC addresses from the base MAC address.

These functions will be used by some follow-up code that'll slot
into if_arge and if_ath.
