Subject: [PATCH 3/8] rt2x00: Minor optimization for devices with RTS/CTS offload
Date: Sun, 20 Feb 2011 13:55:46 +0100 [thread overview]
Message-ID: <201102201355.47592.IvDoorn@gmail.com> (raw)
In-Reply-To: <201102201355.26260.IvDoorn@gmail.com>
From: Helmut Schaa <helmut.schaa@googlemail.com>
Only devices that don't have RTS/CTS offload need to check for
IEEE80211_TX_RC_USE_RTS_CTS and IEEE80211_TX_RC_USE_CTS_PROTECT.
By swapping both conditions we keep the same number of needed conditionals
for devices without RTS/CTS offload but save one conditional on devices
with RTS/CTS offload.
