Linville" Subject: [064/200] mac80211: fix handling of 4-address-mode in ieee80211_change_iface In-Reply-To: <20100701175201.GA2149@kroah.com> Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1540 Lines: 50 2.6.34-stable review patch. If anyone has any objections, please let me know. ------------------ From: Felix Fietkau commit f7917af92024d43bc20bc1afc92de27b0bd0f50b upstream. A misplaced interface type check bails out too early if the interface is not in monitor mode. This patch moves it to the right place, so that it only covers changes to the monitor flags.
