mac80211: add config tweak for tx bursting when using VHT
By default, set BE tx queue TXOP limit to 1.0 in the hostapd config Many vendor drivers are doing similar things to boost throughput. On MT7612 under ideal conditions, it improves tx throughput from 470 Mbit/s to about 570 Mbit/s. Signed-off-by: Felix Fietkau <nbd@nbd.name>
