then td->td_sel is NULL and this will result in a segfault inside selrecord().
This happens when only using kqueue() to poll for read and write events.
If select() and kqueue() is mixed there won't be a segfault.

The code went to a lot of trouble to issue either a start+stop condition
or a repeated start condition only to follow it with a stop condition
and a read(2) call that issues a new start condition.
So, fix the read in I2C_MODE_REPEATED_START mode by using I2CREAD ioctl
within the running transaction. This obviously requires that the slave
address has the read bit set which was not required before.
Another problem was with width parameter of zero and
I2C_MODE_REPEATED_START mode. In that case we issued a repeated start
without any preceding start.
While here, remove the redundant (unused) argument to I2CSTOP throughout
the program.
Also, clarify the meaning of -w option, especially "-w 0", in the manual
page.

As part of ath10k and other chipset support, the EDCA stuff has to be moved
to potentially be per-VAP. For hardware that doesn't support it (ie,
everything that we currently support) it can just fetch the "current"
global EDCA parameters for the NIC.
This is one of those parameters that is linked to the currently active
channel context / VAP in Linux mac80211 parlance.
Tested:
* ath(4), STA and AP modes
The duplicate detection code currently expects A-MSDU frames to be encaped -
they're decap'ed /after/ duplicate detection.
However for ath10k (and iwm hardware later on) the firmware supports
doing A-MSDU decap in hardware - which shows up as multiple frames with
the same sequence number and IV.
This is the first part of decap handling - if we see a stretch of A-MSDU
frames from the driver with the MORE bit set, then don't treat them
as duplicates.
This isn't 100% complete as crypto sequence number handling and "A-MSDU in
A-MPDU" needs handling, but it's a start.
This should be a glorified no-op for everyone. Please tell me if it isn't.
It doesn't seems to be needed anymore and this make ehci working again
on the Pine64.
Thanks to jmcneill@ for the help.
Tested on: Pine64 (A64), OrangePi One (H3), BananapiM2 (A31s)
posix_fallocate is logically equivalent to writing zero blocks to the
desired file size and there is no reason to prevent calling it in
capability mode. posix_fallocate already checked for the CAP_WRITE
right, so we merely need to list it in capabilities.conf.

Define a prototype for exit in stand.h. Provide a reference to exit in
a few conf.c files to ensure that its definition gets pulled in early.
Since exit() is a MD routine, it isn't defined in libsa. However,
libsa tends to be listed last and will soon have panic() in it which
calls exit(). The reference to exit early ensures that the MD exit is
available to satisfy linking for static libraries.
Rename exit to efi_exit. It doesn't have the proper signature and
conflicts with standard definition. Provide the standard definition as
well.

tmpfs uses unr(9) to allocate inodes. Previously when unmounting it
would individually free the units when it freed each vnode. This is
unnecessary as we can use the newly-added unrhdr_clear function to clear
out the unr in onde go. This measurably reduces the time to unmount a
tmpfs with many files.

Previously before you could call unrhdr_delete you needed to
individually free every allocated unit. It is useful to be able to tear
down the unr without having to go through this process, as it is
significantly faster than freeing the individual units.
