When there's a bt-wifi contention that requires arbitration,
we use a priority-based mechanism to decide which comm wins.
Over time, use cases become more and more complex, with multiple
concurrent active links with different traffic types and different QoS
requirements, on both WiFi and BT sides.
This, in turn, requires us to elaborate our prioritization mechanism.
However, our legacy products included hw that does not supports this,
so selectively enable this on specific hw - as signaled by the firmware.

The split of iwlwifi into DVM and MVM was a long time ago now,
so we can remove the "default IWLWIFI" that we had to keep all
existing .config files with working defaults during the split.
This is no longer necessary, practically nobody should now be
upgrading a .config that's older than the split.

802.11ac allows A-MSDU that can be up to 12KB long. Since
an entire A-MSDU needs to fit into one single Receive
Buffer (RB), add support for big RBs.
Since this adds lots of pressure to the memory manager and
significantly increase the true_size of the RX buffers,
don't enable this by default.

This is a workaround to an OTP bug. In Series 8000 1x1, the OTP
0xA052 defines 2x2 antenna configuration. This workaround overrides
the decision based on HW id and on MIMO disabled bit which is
correct in the OTP and set to disabled. This fixes the previous
workaround "force 1x1 antenna in Series 8000".

When entering D3, we need to use hardcoded key indices because the
firmware requires that.  To do so, we are overwriting the HW key index
in the keyconf structure, which makes it impossible to reuse the
indices that were used before entering D3.  Additionally, we overwrite
all the non-PTK keys with index 1, because the firmware only allows
one non-PTK key to be set.  This is bad, because when we resume, we
may try to set more than one key with index 1, which will obviously
fail.

To fix this, allow the callers to set a pre-defined index to use in
iwl_mvm_set_sta_key() instead of relying on the hw_key_idx value from
the keyconf struct (which requires overwriting it).  In normal cases,
the caller can pass STA_KEY_IDX_INVALID, which will cause a new key
offset to be chosen.  During HW_RESTART, we pass the offset that is in
use.  And during D3 entry, we pass the hardcoded indices we need to
use.

Additionally, don't clear the fw_key_table in D3 entry, so that the
flags are still set with the pre-D3 values when exiting D3.
