+Subject: [PATCH 112/116] mtk: wifi: mt76: mt7996: enable ampdu limit to avoid
+ BA bound issue
+
+[Description]
+When the station is MTK device and the peak is higher than 15G, the PPS
+would exceed HW-RRO's bandwidth and lead to Rx fifo full and PER. When
+a link occurs PER, it may occupy SSN and the other two bands are not
+able to transmit.
+
+Limit AMPDU to 512 when satisify all of the following conditions
+1. BA winsize is 1024.
+2. At least one link use BW320 and its spatial stream is larger
+than 3.
+3. At least one link use BW160 and its spatial stream is larger
+than 3.
+
+By limiting AMPDU to 512, it can solve this issue.
+1. Reduce PPS so we can avoid Rx fifo full due to HW-RRO.
+2. If a bind occupy SSN, the other two bands can use the SSN
+between 512 to 1024.
