From cabb550e2b97b8ea42124a93d4665ca052f3e3ff Mon Sep 17 00:00:00 2001 From: Jes Sorensen Date: Thu, 14 Apr 2016 16:37:17 -0400 Subject: [PATCH] rtl8xxxu: Fix 8188RU support The 8188RU does not like PAPE to be enabled, while all the other gen1 parts seem to require it. This makes the RTL8188RU able to associate for me.
