This is intended for use in KTLS transmit where each TLS record is
described by a single mbuf that is itself queued in the socket buffer.
Using the existing CRYPTO_BUF_MBUF would result in
bus_dmamap_load_crp() walking additional mbufs in the socket buffer
that are not relevant, but generating a S/G list that potentially
exceeds the limit of the tag (while also wasting CPU cycles).

It turns out that, silly adrian, setting it to 64 means only two
AMPDU frames of 32 subframes each. Thus, whilst those are in-flight,
any subsequent queues frames to that node get dropped.
This ends up being pretty no bueno for performance if any receive
is also going on at that point.
Instead, set it to 128 for the time being to ensure that SOME
frames get queued in the meantime. This results in some frames
being immediately available in the software queue for transmit
when the two existing A-MPDU frames have been completely sent,
rather than the queue remaining empty until at least one is sent.
It's not the best solution - I still think I'm scheduling receive
far more often than giving time to schedule transmit work -
but at least now I'm not starving the transmit side.
Before this, a bidirectional iperf would show receive at ~ 150mbit/sec.
but the transmit side at like 10kbit/sec. With it set to 128 it's
now 150mbit/sec receive, and ~ 10mbit receive. It's better than 10kbit/sec,
but still not as far as I'd like it to be.
Tested:
* AR9380/QCA934x (TL-WDR4300 AP), Macbook pro test STA + AR9380 test STA
I've been using STA+AP modes at home for a couple years now
and I've been finding and fixing a lot of weird corner cases.
This is the eventual patchset I've landed on.
* Don't force beacon resync in STA mode if we're using sw beacon tracking.
This stops a variety of stomping issues when the STA VAP is reconfigured;
the AP hardware beacons were being stomped on!
* Use the first AP VAP to configure beacons on, rather than the first VAP.
This prevents weird behaviour in ath_beacon_config() when the hardware
is being reconfigured and the STA VAP was the first one created.
* Ensure the beacon interval / timing programming is within the AR9300
HAL bounds by masking off any flags that may have been there before
shifting the value up to 1/8 TUs rather than the 1 TU resolution the
previous chips used.
Now I don't get weird beacon reprogramming during startup, STA state
changes and hardware recovery which showed up as HI-LARIOUS beacon
configurations and STAs that would just disconnect from the AP very
frequently.
Tested:
* AR9344/AR9380, STA and AP and STA+AP modes
If a regulator hasn't been enable by a driver but is enabled in hardware
(most likely enabled by U-Boot), regulator_status will returns that it
is enabled and so any call to regulator_disable will panic as it wasn't

For the discovery phase of SD/eMMC we need to do some transaction in a async
way.
The classic CAM XPT_{GET,SET}_TRAN_SETTING cannot be used in a async way.
This also allow us to split the discovery phase into a more complete state
machine and we don't mtx_sleep with a random number to wait for completion
of the tasks.
For mmc_sim we now do the SET_TRAN_SETTING in a taskqueue so we can call
the needed function for regulators/clocks without the cam lock(s). This part is
still needed to be done for sdhci.
We also now save the host OCR in the discovery phase as it wasn't done before and
only worked because the same ccb was reused.

* card does not support write-one-to-clear semantics for interrupt status

* MDIO operations can take longer to complete
