Subject: [PATCH AUTOSEL 5.12 13/49] mt76: mt7921: fix max aggregation subframes setting

From: Felix Fietkau <[email protected]>

[ Upstream commit 94bb18b03d43f32e9440e8e350b7f533137c40f6 ]

The hardware can only handle 64 subframes in rx direction and 128 for tx.
Improves throughput with APs that can handle more than that
