[PATCH v2 2/2] brcmfmac: make firmware frameburst mode a module parameter

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

 



This patch is for adding a new module parameter "frameburst".
With setting "frameburst=1" in module parameters, firmware frameburst mode
will be enabled. The feature can enable per-packet framebursting in
firmware side and get higher TX throughput in High Throughput(HT) mode.
