It is now possible to send BREAK commands to vmd(8) independently of
the serial terminal emulator.
Happy virtual ddb(4) hacking!

This will be soon be used to emulate BREAK commands in vmd(8).

corresponding user mode ioctls.
If the master part of the pseudo terminal previously enabled TIOCUCNTL,
it will now receive the TIOCUCNTL_{S,C}BRK commands. This allows to
send BREAKS commands over a pty(4) independently of the serial terminal
emulator used.

the assembly code in libcrypto assumes unaligned access is allowed for
ARMv7. Make these paths conditional on __STRICT_ALIGNMENT not being
defined and define __STRICT_ALIGNMENT in arm_arch.h for OpenBSD.

This extern variable appears not to be used.
And it is overridden by local variable in doConnection().
This causes MSVC warning C4459 "declaration of 'verify_error'

If the Rx channel goes down with pending data on the ring, toss the pending
data to ensure that the firmware's rx ring head index matches the rx ring
tail index. Otherwise we trigger an interrupt storm since vldcpread() never
consumes pending data while the channel is down, and the firmware keeps
triggering the interrupt until all data on the ring is consumed.
Interrupt storm observed and fix tested on a T5220 (which can now run
ldom guests; without this fix starting ldomd would trigger the problem).

This was changed a decade ago to forcibly try table 3 first in order
to make some now-long-gone hardware work.
Newer Lenovo machines seem to have trouble being asked to change
modes which manifests as a long boot delay as it waits for each
request to timeout, or by causing the keyboard to generate junk when
typing.
Assume table 2 by default and just leave it alone if it's already
there. This is how Linux has operated for quite a while and seems
to help on these Lenovo machines.
Tested by a few with these machines and has been in snaps for a bit.

phessler@ has been having trouble with msk on overdrive 1000s. some
of the issues relate to the driver not coping with exhaustion of
mbufs for the rx ring, the other issues are corruption of the mcl9k
pool that msk uses.
this diff adds a timeout that the rx refill code uses when the rx
ring is empty and cannot be filled. it'll periodically retry the
ring refill until it can get some mbufs in the air again.
the current code made hunting for the mcl9k issue too hard, so this
rewrites it to be simpler and more like other drivers. there's now
just arrays of mbuf pointers and dmamaps to shadow the hardware
ring entries, and producer and consumer indexes. what was there
before had linkes lists of something to hold mbuf pointers and
dmamaps, and some way to go from the ring to go back to that. i
think, it was hard to tell what was happening.
this also copies the ADDR64 handling on the tx ring to the rx ring.
this potentially makes more rx descriptors available, but that can
happen later.
in hindsight the mcl9k problem could have been from letting if_rxr
allocate the entier ring. if every descriptor was filled, the chip
may have run around the ring when it shouldnt have. giving rxr one
less descriptor than there is on the ring may have fixed the problem
too.
this work also makes it easier to make msk mpsafe.

we typically have about four flowrings per priority. As access point
we apparently need one, or four considering the priorities, flowrings
per client. For now let's start with a single TX flowring. To setup
a flowring we need to send a create request and can only start sending
packets as soon as we are told that the ring is created. With this we
can now do actual network traffic.

happens when we successfully associate and the AP tries to initiate the
WPA2 handshake but we haven't received the asynchronous ASSOC event yet.
Dropping the packet will make the AP retry, and at that point we should
have successfully associated. While there, don't feed the event packets
to our network stack. It's been helpful for debugging but now it's time
to let go.
