First two patches are to refine SER timer and IMR to have expected SER behavior. RX tag is a sequence number belong to a RX DMA data, and WiFi 7 chips need to validate this tag before reading DMA content. This happens rarely, and no obvious impact with throughput. The last patch is to enlarge RX buffer size to plus RX descriptor size to receive a 11454-byte RX packet. Though we still can receive this kind of packet with smaller buffer size, use suitable size can get better performance.
