1) They are using wrong tag (Tx) + map (Rx) combination.
2) Rx descriptor is already synchronized in iwn_notif_intr()
3) It's not needed for transmitted data since device does not change
mbuf contents.
Tested with Intel 6205 (amd64), STA mode.
Newer VGAs don't support any mono modes, but bugs in the tables created
2 virtual mono modes (#45 90x43 and #112 80x43) that behaved more
strangely than crashing. 90-column modes are tweaked 80-column ones
and also fail to work on newer VGAs. #45 did crash (hang) on some
hardware.
it to a separate state for each CPU.
Terminal "input" is user or kernel output. Its state includes the current
parser state for escape sequences and multi-byte characters, and some
results of previous parsing (mainly attributes), and in teken the cursor
position, but not completed output. This state must be switched for kernel
output since the kernel can preempt anything, including itself, and this
must not affect the preempted state more than necessary. Since vty0 is
shared, it is necessary to affect the frame buffer and cursor position and
history, but escape sequences must not be affected and attributes for
further output must not be affected.
This used to work. The syscons terminal state contained mainly the parser
state for escape sequences and attributes, but not the cursor position,
and was switched. This was first broken by SMP and/or preemptive kernels.
Then there should really be a separate state for each thread, and one more
for ddb, or locking to prevent preemption. Serialization of printf() helps.
But it is arcane that full syscons escape sequences mostly work in kernel
printf(), and I have never seen them used except by me to test this fix.
They worked perfectly except for the races, since "input" from the kernel
was not special in any way.
This was broken to use teken. The general switch was removed, and the
kernel normal attribute was switched specially. The kernel reverse
attribute (config option SC_CONS_REVERSE_ATTR) became unused, and is
still unusable because teken doesn't support default reverse attributes
(it used to only be used via the ANSI escape sequence to set reverse
video).
The only new difficulty for using teken seems to be that the cursor
position is in the "input" state, so it must be updated in the active
input state for each half of the switch. Do this to complete the
restoration.
The per-CPU state is mainly to make per-CPU coloring work cleanly, at
a cost of some space. Each CPU gets its own full set of attribute
(not just the current attribute) maintained in the usual way. This
also reduces races from unserialized printf()s. However, this gives
races for serialized printf()s that otherwise have none. Nothing
prevents the CPU doing the a printf() changing in the middle of an
escape sequence.
Some code was additionally moved for (future) lock splitting.
Tested with Intel 6205, STA mode.

Do not try to use errno(2) codes here; instead, just return unique
value (1) when radio is disabled via hardware switch and another
one (-1) for any other error in initialization path.
Tested with Intel 6205, STA mode.
This can significantly reduce scan duration thus saving time and power.
EBS failure reported by FW disables EBS for current connection. It is
re-enabled upon new connection attempt on any WLAN interface.

Add support for early boot access to NVRAM variables, using a new
bhnd_nvram_data_getvar_direct() API to support zero-allocation direct
reading of NVRAM variables from a bhnd_nvram_io instance backed by the
CFE NVRAM device.

r315083 essentially reverted r263954 which was made for a good reason,
but didn't take into account AACRAID_DEBUG.
Now both types of build should be clean.

Let firmware do its best first, and if it can't, try software recovery.
I would remove software timeout handler completely, but found bunch of
complains on command timeout on sparc64 mailing list few years ago, so
better be safe in case of interrupt loss.
