TCB. Filters are programmed by modifying the TCB too (via a different
routine) and the reply to any TCB update is delivered via a
CPL_SET_TCB_RPL. Figure out whether the reply is for a filter-write or
something else and route it appropriately.

mutex protects the list of ssc disks, and each ssc disk has a mutex
to protect it's bioq.

tick until the situation is resolved (if ever), just print a single

- When adding more swap, warn if the total amount exceeds half the
theoretical maximum we can handle.
Add timeout to wait for network controllers to appear when netbooting.
USB ethernet adapter initialization usually is delayed and
they're not available immidiately after autoconfiguration. So we need
to wait a bit before giving up

iterate lock.
This causes LORs and deadlocks as some code paths will have the com lock
held when calling ieee80211_iterate_nodes().
Here, the comlock isn't held during the node table and node iteration
locks; and the callback isn't called with any (extra) lock held.

"m_getjcl:invalid cluster type" that occurred some
time back with the igb driver. This happens often when
booting over the net. I believe the NIC hardware is left
in a warm state when handed over to the driver, and a stray
RX interrupt happens earlier than the code is prepared for
it to happen. This change was verified to fix the problem,
its kind of a bandaid... but it is similar to what was done
in the igb code.
1) It is not useful to call "devfs_clear_cdevpriv()" from
"d_close" callbacks, hence for example read, write, ioctl and
so on might be sleeping at the time of "d_close" being called
and then then freed private data can still be accessed.
Examples: dtrace, linux_compat, ksyms (all fixed by this patch)
2) In sys/dev/drm* there are some cases in which memory will
be freed twice, if open fails, first by code in the open
routine, secondly by the cdevpriv destructor. Move registration
of the cdevpriv to the end of the drm open routines.
3) devfs_clear_cdevpriv() is not called if the "d_open" callback
registered cdevpriv data and the "d_open" callback function
returned an error. Fix this.

These functions are used to grab the softc from
auto-free and to free the softc back to the correct
malloc type, respectivly.

* the descriptor ID, and
* the multi-buffer support that the EDMA chips support.
This is required for successful MAC transmission of multi-descriptor
frames. The MAC simply hangs if there are NULL buffers + 0 length pointers,
but the descriptor did have TxMore set.
This won't be done for the 11n aggregate path, as that will be modified
to use the newer API (ie, ath_hal_filltxdesc() and then set first|middle|
last_aggr), which will deprecate some of the current code.
TODO:
* Populate the numTxMaps field in the HAL, then make sure that's fetched
by the driver. Then I can undo that hack.
Tested:
* AR9380, AP mode, TX'ing non-aggregate 802.11n frames;
* AR9280, STA/AP mode, doing aggregate and non-aggregate traffic.
