which the tty device can disappear. Check for this and return ENXIO
back up the call chain so that callers can cope.
This closes a race where TF_GONE would get set while buffers were being
allocated as part of ttydev_open(), causing a subsequent call to
ttydevsw_modem() later in ttydev_open() to assert.

Before this patch is was only enforced that the length in the header
is not larger then the buffer length.

I added IEEE80211_TX_LOCK() a few years ago because there were races between
seqno allocation, driver queuing and crypto IV allocation. This meant that
they'd appear out of sequence and the receiver would drop them, leading to
terrible performance or flat out traffic hangs.
This flag should be set by drivers that do their own sequence number
allocation for all frames it needs to happen for, including beacon frames.
Eventually this should lead to the driver taking care of locking for
allocating seqno and other traffic-triggered events (eg addba setup.)
This is the bulk of the magic to start enabling VHT channel negotiation.
It is absolutely, positively not yet even a complete VHT wave-1 implementation.
* parse IEs in scan, assoc req/resp, probe req/resp;
* break apart the channel upgrade from the HT IE parsing - do it after the
VHT IEs are parsed;
* (dirty! sigh) add channel width decision making in ieee80211_ht.c htinfo_update_chw().
This is the main bit where negotiated channel promotion through IEs occur.
* Shoehorn in VHT node init ,teardown, rate control, etc calls like the HT
versions;
* Do VHT channel adjustment where appropriate
Tested:
* monitor mode, ath10k port
* STA mode, ath10k port - VHT20, VHT40, VHT80 modes
TODO:
* IBSS;
* hostap;
* (ignore mesh, wds for now);
* finish 11n state engine - channel width change, opmode notifications, SMPS, etc;
* VHT basic rate negotiation and acceptance criteria when scanning, associating, etc;
* VHT control/management frame handling (group managment and operating mode being
the two big ones);
* Verify TX/RX VHT rate negotiation is actually working correctly.
Whilst here, add some comments about seqno allocation and locking. To achieve
the full VHT rates I need to push seqno allocation into the drivers and
finally remove the IEEE80211_TX_LOCK() I added years ago to fix issues. :/
This sets up:
* vht capabilities in vaps;
* calls vht_announce to announce VHT capabilities if any;
* sets up vht20, vht40 and vht80 channels, assuming the regulatory code
does the right thing with 80MHz available ranges;
* adds support to the ieee80211_add_channel_list_5ghz() code to populate
VHT channels, as this is the API my ath10k driver is using;
* add support for the freq1/freq2 field population and lookup that
VHT channels require.
The VHT80 code assumes that the regulatory domain already has limited VHT80
bands to, well, 80MHz wide chunks.

These are of the few cases where we use the GCC non-null attributes in
non-header code. As part of a review [1] of our use of such attributes we
are replacing such uses of the overly aggressive GCC attribute with clang's
_Nonnull attribute.
In this case the attributes serve little purpose as they just don't
enforce run time checks, If anything the attributes would cause NULL pointer
checks to be ignored but there are no such checks so only effect is
cosmetic.
The references appear to be left over from code development and likely
already fulfilled their purpose.

Tested using lrzsz and a null-modem cable. The ExpressCard/34
variants containing the MCS9922 should also use MSI with this change.
