- Delete all chipc children on attachment failure.
- Added missing bhnd_nexus bhnd_bus_deactivate_resource implementation.
- Drop a CHIPC_UNLOCK() accidentally left behind after lifting
synchronization into the chipc region refcounting API.
- Fix re-allocation of chipc resources. Previously, the resource ID was
reset to -1 on release, preventing later re-allocation.

Inserting a full mbuf with an external cluster into the socket buffer
resulted in sbspace() returning -MLEN. However, since sb_hiwat is
unsigned, the -MLEN value was converted to unsigned in comparisons. As a
result, the socket buffer was never autosized. Note that sb_lowat is signed
to permit direct comparisons with sbspace(), but sb_hiwat is unsigned.
Follow suit with what tcp_output() does and compare the value of sbused()
with sb_hiwat instead.

This reduces the size of kaiocb slightly. I've also added some generic
fields that other backends can use in place of the BIO-specific fields.
Change the socket and Chelsio DDP backends to use 'backend3' instead of
abusing _aiocb_private.status directly. This confines the use of
_aiocb_private to the AIO internals in vfs_aio.c.

When allocating a new mbuf or bus_dmamap_load()-ing it fails,
we can just keep the old mbuf since we are dropping that packet anyway.
Instead of doing bus_dmamap_create() and bus_dmamap_destroy() all the time,
create an extra bus_dmamap_t which we can use to safely try
bus_dmamap_load()-ing the new mbuf. On success we just swap the spare
bus_dmamap_t with the data->map of that ring entry.
Tested:
Tested with Intel AC7260, verified with vmstat -m that new kernel no
longer visibly leaks memory from the M_DEVBUF malloc type.
Before, leakage was 1KB every few seconds while ping(8)-ing over the wlan
connection.

For DWC_GMAC_ALT_DESC implementations, the multicast hash table has only
64 entries. Instead of 8 registers starting at 0x500, a pair of registers
at 0x08 and 0x0c are used instead.

Some later code I'll commit pushes lists of frames into the EDMA TX
FIFO, rather than a single frame at a time. The CABQ code already
pushes frame lists, but it turns out we should actually be doing it
in general or performance tanks. :(
Since key table is cleared on every device shutdown,
static WEP keys (which are set only once) need to be
reinstalled manually every time when device starts running.
Tested with RTL8188EU, STA (all ciphers) / IBSS (WPA-none) modes.
r298930 removed the inittodr call, but it seems like this prevents
"calcru: runtime went backwards ..." messages from occasionally appearing
when resuming from migration.

ticks are signed int and if statistics is not updated for a long time
(more than INT_MAX ticks, but less than UINT_MAX) difference becomes
negative and less than hz for a long time.
Other option to repeat is simply load driver (which initializes
timestamps to 0) when ticks are negative.

The SYSINIT runs at SI_SUB_KICK_SCHEDULER after the scheduler is fully
initialized and timers are working. This fixes booting in the
EARLY_AP_STARTUP case.
A couple of mostly cosmetic fixes for the final initialization of netfront:
- Switch to "connected" state before starting to kick the rings.
- Correctly use "rxq" in the initialization loop (previously rxq was not
updated in the loop, and netfront would kick np->rxq[N] several times).
- Declare and define xn_connect as static, it's not used outside of this
file.
