Before, only frames with a maximum size of 1528 bytes could be
transmitted between two 802.11s nodes.
For batman-adv for instance, which adds its own header to each frame,
we typically need an MTU of at least 1532 bytes to be able to transmit
without fragmentation.
This patch now increases the maxmimum frame size from 1528 to 1656
bytes.
Tested with two ath10k devices in 802.11s mode, as well as with
batman-adv on top of 802.11s with forwarding disabled.
Fix originally found and developed by Ben Greear.

Function ep_rx_complete is being called without NULL checking
in ath10k_htc_rx_completion_handler. Without such check, mal-
formed packet is able to cause jump to NULL.
ep->service_id seems a good candidate for sanity check as it is

let firmware request multiple blocks of DMA memory with smaller size.

Do not delete a key cache entry that is still being referenced by
pending frames in TXQs. This avoids reuse of the key cache entry while a
frame might still be transmitted using it.
To avoid having to do any additional operations during the main TX path
operations, track pending key cache entries in a new bitmap and check
whether any pending entries can be deleted before every new key
add/remove operation. Also clear any remaining entries when stopping the
interface.

It is possible for there to be pending frames in TXQs with a reference
to the key cache entry that is being deleted. If such a key cache entry
is cleared, those pending frame in TXQ might get transmitted without
proper encryption. It is safer to leave the previously used key into the
key cache in such cases. Instead, only clear the MAC address to prevent
RX processing from using this key cache entry.
This is needed in particularly in AP mode where the TXQs cannot be
flushed on station disconnection. This change alone may not be able to
address all cases where the key cache entry might get reused for other
purposes immediately (the key cache entry should be released for reuse
only once the TXQs do not have any remaining references to them), but
this makes it less likely to get unprotected frames and the more
complete changes may end up being significantly more complex.

Now that all the needed pieces are in place implement suspend support QCA6390
PCI devices. All other devices will return -EOPNOTSUPP during suspend. The
suspend is implemented by switching the firmware to WoW mode during suspend, so
the firmware will be running on low power mode while host is in suspend.
At the moment we are not able to shutdown and fully power off the device due to
bugs in MHI subsystem, so WoW mode is a workaround for the time being.
During suspend we enable WoW mode, disable CE irq and DP irq, then put MHI to
suspend state. During resume, driver resumes MHI firstly, then enables CE irq
and dp IRQ, and sends WoW wakeup command to firmware.

return credit, the suspend_complete message doesn't send to host but is
dropped. So host gets time out and WoW suspend failed.

restart_work is very easy to break the 1st restart work and lead
recovery fail.
Add a flag to allow only one restart work running untill
device successfully recovered.
It already has flag ATH10K_FLAG_CRASH_FLUSH, but it can not use this
flag again, because it is clear in ath10k_core_start. The function
ieee80211_reconfig(called by ieee80211_restart_work) of mac80211 do
many things and drv_start(call to ath10k_core_start) is 1st thing,
when drv_start complete, it does not mean restart complete. So it
add new flag and clear it in ath10k_reconfig_complete, because it
is the last thing called from drv_reconfig_complete of function
ieee80211_reconfig, after it, the restart process finished.

In some devices difference in chip-id should be enough to pick
the right BDF. Add another support for chip-id based BDF selection.
With this new option, ath10k supports 2 fallback options.
The board name with chip-id as option looks as follows
board name 'bus=snoc,qmi-board-id=ff,qmi-chip-id=320'

Assure that frames with the fixed order flag are not reordered
relative to each other. This is accomplished by transmitting them
using a fixed priority independent of their QoS field.

Currently 256 bitmap in blockack frames is being set only for AP mode.
Fix this to set whenever beacon has changed and has HE capability, there
by supporting mesh as well.

HE operation IE in beacons is constructed based on userspace params,
which firmware might not be aware of. This causes firmware not to
configure TXOP duration based RTS threshold which could cause mismatch
in behaviour with respect to what is being advertised in beacons. This
patch sends HE operation IE fetched from beacon to firmware using
WMI interface for configuration.
