2021-10-20mt76: mt7915: fix mgmt frame using unexpected bitrateSean Wang
Fix the current driver mgmt frame is not respecting the basic rates field provided by the AP and then unconditionally is using the lowest (1 or 6 Mbps) rate. For example, if the AP only supported basic rate {24, 36, 48, 54} Mbps, mt7921 cannot send mgmt frame with the rate not in the group. So, instead, we pick up the lowest basic rate the AP can support to send.
