From 62ae67be31c2346b6d74653a148ddbd1b9a94424 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 18 Nov 2009 18:42:05 +0100 Subject: [PATCH] mac80211: remove encrypt parameter from ieee80211_tx_skb Since the flags moved into skb->cb, there's no longer a need to have the encrypt bool passed into the function, anyone who requires it set to 0 (false) can just set the flag directly.
