From 61486e0f68d1f8966c09b734566a187d42d65c54 Mon Sep 17 00:00:00 2001 From: Ivo van Doorn Date: Sat, 10 May 2008 13:42:31 +0200 Subject: rt2x00: Remove ieee80211_tx_control argument from write_tx_desc() Move the last remaining information details read from ieee80211_tx_control in the drivers to the txentry_desc structure. After this we can remove ieee80211_tx_control from the argument list for the callback function, which makes it easier when the control information is moved into skb->cb Signed-off-by: Ivo van Doorn Signed-off-by: John W.
