From: Tzu-En Huang <redacted> [ Upstream commit ee755732b7a16af018daa77d9562d2493fb7092f ] The vht capability of MAX_MPDU_LENGTH is 11454 in rtw88; however, the rx buffer size for each packet is 8192. When receiving packets that are larger than rx buffer size, it will leads to rx buffer ring overflow.
