This just stores pointers to the IE; it doesn't yet parse anything.
Note: it blows out the size of ieee80211_node, so this will require
ye olde kernel/modules recompile.
* Obey the peer A-MPDU density if it's larger than the currently configured
one.
* Pay attention to the peer A-MPDU max-size and don't assume we can transmit
a full A-MPDU (64k!) if the peer announces smaller values.
Relnotes: ath(4): Fix A-MPDU transmit; obey A-MPDU density and max size.
* Pepper comments around which describe what state(s) we're in when faking
up 11n nodes.
* By default don't fake it up as 11n until we properly negotiate the 11n
capabilities using probe request/response frames.
* Send a probe request with our HT information, as the 802.11-2012 spec
suggests.
* Reassociate with the driver if we've been promoted.
This is done because although learning a peer via beacons can learn 11n
state, learning peers via hearing probe frames and broadcast frames
does not. Thus, sometimes you end up with an 11n peer in the peer
table and sometimes you don't.
Note that the probe request/response exchange may not actually succeed.
Ideally we'd put the peer into some blocking state until we've exchanged
probe request/reponse to learn capabilities, or we timeout and just
stay non-11n.
This is more an experiment to get 11n IBSS nodes actually discovering
each other and be able to transmit. There are other issues that creep
up which I'll attempt to address in future commits.
Tested:
* AR9380 NICs in 11n mode.

This avoids the time-warp after kthreads have started running and the
required fixup to td_slptick and td_blktick in the EARLY_AP_STARTUP
case. Now, 'ticks' is initialized before any kthreads are created or
any context switches are performed.

The default pkg(8) from pkg.freebsd.org requires libjail.so,
so mark the jail package as vital along with the runtime
package to avoid errors when libjail.so is removed. This is
a no-op for systems with WITHOUT_JAIL in src.conf(5) and pkg(8)
built from the Ports Collection.
In order to make this work without marking packages such as
the jail-lib32, for example, the jail.ucl file needed to be
split out into separate files similarly to the runtime-*.ucl
files.

many borken middle-boxes tend to do that. But during 3whs, in syncache_expand(),
we don't do that which causes us to send a RST to such a client. Relax this
constraint by only using tsecr to compare against timestamp that we sent when it
is not 0. As a result, we'd now accept the final ACK of 3whs with tsecr of 0.

This patch allows to specify PHY register offset for ukswitch. For instance,
switch MAICREL KS8995XA connected via MDIO to SoC, but PHY register starts
at 1. So hint for this case is: hint.ukswitch.0.phyoffset=1
No change/effect if hint is not set.

to allow arm64 servers with ACPI to use it over FDT.

(hopefully) stock gcc 4.2.1 on i386 and other arches.
In particular:
- Do not use %ebx in the asm constraints on i386, since rtld is
compiled with -fPIC and gcc cannot handle GOT-base register reload
(clang and newer gcc can).
- Avoid direct use of [static N] construct in the function
declaration/definion. In-tree gcc was patched to support this, but
stock 4.2.1 cannot handle the feature.

the driver will check the appropriate field in the id_aa64isar0_el1

When wcstof() skipped initial space and then parsing failed, it set
endptr to the first non-space character. Fix it to correctly report
failure by setting endptr to the beginning of the input string.
The fix is from theraven@, who fixed this bug in wcstod() and
wcstold() in r227753.
While I'm here:
Move assignments out of declarations in wcstod() and wcstold().
This is against my personal preference, but it is our agreed style(9).
Set endptr correctly on malloc() failure in all three functions.
Remove an incorrect comment: This is pointer arithmetic,
so the code was not actually making that assumption.
wcstold() advanced the wcp pointer beyond leading whitespace
and then reset it back to the beginning of the string.
Do not reset it. This seems to have no functional effect,
since strtold_l() also skips leading whitespace. I'm making
the change to keep this function consistent with wcstof() and
wcstod(), and because the C11 spec prescribes the use of iswspace()
to skip leading space.

vmpage requires struct pmap to exist and contain a pm_stats field. As of
r308817, either AIM or BOOKE is required to be set in order to get their
respective pmap structs. Rather than expose them both, or try to unify them
unnecessarily, add a third option which contains only a pm_stats field, and
change the two existing pmap structures to place the common fields at the
beginning of the struct. This actually fixes the stats collection by libkvm on
AIM hardware, because before it was accessing a possibly different offset, which
would cause it to read garbage.
Bump __FreeBSD_version to denote this ABI change, so that ports which depend on
libkvm can be rebuilt.
