[PATCH 4/4] mwifiex: modify TX buff size for SD8887

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



FW crash has been observed while running iperf TX with SD8887
devices. This is because of invalid TX buffer setting. SD8887
supports 2K buffer sizes. This patch fixes this issue.
