From 2c0133a437905591cdaa39cf65a3f7188d20a094 Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Fri, 18 May 2012 07:46:36 +0300 Subject: wlcore/wl12xx/wl18xx: introduce quirk to remove TKIP header space 18xx chips do not require extra space in the TKIP header. Introduce a new HW quirk to allow us to make this feature arch-specific. 12xx chip will now have this quirk.
