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.

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.

This should also help with merging this with the ofwpci driver, with

the driver will check the appropriate field in the id_aa64isar0_el1
