2022-03-16mt76: fix wrong HE data rate in sniffer toolDeren Wu2-4/+8
Due to the missing IEEE80211_RADIOTAP_HE_DATA1_BW_RU_ALLOC_KNOWN in status report, the HE rate in wirehsark/tcpdump always shows wrong value. Applications will refer to IEEE80211_RADIOTAP_HE_DATA5_DATA_BW_RU_ALLOC when the flag is set and shows the correct data rate.

2022-03-16mt76: fix monitor mode crash with sdio driverDeren Wu1-1/+1
mt7921s driver may receive frames with fragment buffers. If there is a CTS packet received in monitor mode, the payload is 10 bytes only and need 6 bytes header padding after RXD buffer. However, only RXD in the first linear buffer, if we pull buffer size RXD-size+6 bytes with skb_pull(), that would trigger "BUG_ON(skb->len < skb->data_len)" in __skb_pull(). To avoid the nonlinear buffer issue, enlarge the RXD size from 128 to 256 to make sure all MCU operation in linear buffer. [ 52.007562] kernel BUG at include/linux/skbuff.h:2313!
