From 9ad9a26e7b7b6671a9aefbb1edb2e8a9ed50ee8d Mon Sep 17 00:00:00 2001 From: Bob Copeland Date: Wed, 29 Oct 2008 08:30:54 -0400 Subject: [PATCH] ath5k: enable hardware encryption for WEP This change re-enables hardware encryption for ath5k after setting up mac80211 to handle the initialization vectors which happens to make it work. Add a module param (nohwcrypt) to optionally turn it off. Signed-off-by: Bob Copeland Signed-off-by: John W.
