Subject: [PATCH] rtw88: increse the size of rx buffer size
Git-commit: ee755732b7a16af018daa77d9562d2493fb7092f
Patch-mainline: v5.10-rc1
References: git-fixes
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.
