[PATCH 15/20] rtl8180: add ERP configuration for rtl8187se

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

 



This patch adds ERP configuration support for rtl8187se to the
existing ERP configuration function.
It needs a different register offset and it must not apply
rtl8185 workaround.
