From 355668d23a99acb45fefd7aeee8e0881e953e432 Mon Sep 17 00:00:00 2001 From: Andrea Merello Date: Wed, 26 Mar 2014 21:03:03 +0100 Subject: [PATCH] rtl8180: add ERP configuration for rtl8187se 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. Signed-off-by: Andrea Merello Signed-off-by: John W.
