For a variant of mt7916, it supports up to 3 tx/rx paths but only 2
spatial streams. This implies that it has one more path to support
beamform. The correct tx/rx path number shall be configured to make sure
beamform works properly.

The MIB INFO command is fetching MIB_BUSY_TIME, MIB_TX_TIME, MIB_RX_TIME and
MIB_OBSS_AIRTIME from the radio and filling out cc_busy, cc_tx, cc_bss_rx
and cc_rx respectively.
busy should be >= tx + rx >= tx + bss_rx but we don’t always quite see this.
Sometimes tx + rx is a bit higher than busy due to inaccurate accounting,
so this patch recalculates numbers to make them more reasonable.

In previous, we only allow user to configure tx antenna mask
contiguously (e.g. 0x3, 0xf).
This patch allows user to configure tx antenna mask interleavingly
(e.g. 0x5, 0x8). By setting proper antenna mask and nss, user can
prioritized the signal of different antennas, which helps to test
their performance in normal mode.

Previously the code used skb_set_queue_mapping for management or non-bufferable
powersave frames that need to be sent to a different hardware queue.
This can confuse AQL, which expects the value to remain the same until the tx

The only place that currently uses the altered skb queue mapping is the txwi
write function. Change the code to pass the hardware queue id as a function
parameter instead.
