When per-packet rate reporting is enabled, the hardware can get stuck under some conditions. It self-recovers quickly, but in practice this leads to reduced performance. In order to avoid running into this issue, disable per-packet rate reporting by default and query the rx rate from firmware instead, unless monitor mode is enabled.

In the MT7915 info, the fields for the WLAN index / queue overlap with the token id, and the MT_TX_FREE_PAIR bit indicates, which one is present. If MT_TX_FREE_PAIR is set, skip processing the token index, since the data will not be valid. This fixes accidentally freeing tokens which are still in use by the hardware with a wrong station pointer. Signed-off-by: Felix Fietkau <nbd@nbd.name>

When looking for a MAC address slot, start by using main BSSID slots 1-3, afterwards use 16 repeater mode BSSID slots, then start using the slots usually used for AP mode.

This is primarily for testing and can be used in combination with monitor mode to make the card respond to packets sent to a specific MAC address.
