Subject: [PATCH 23/28] iwlwifi: Endianity fix for frame control
Date: Wed,  8 Aug 2007 15:33:40 +0800	[thread overview]
Message-ID: <1186558479530-git-send-email-yi.zhu@intel.com> (raw)
In-Reply-To: <11865584771950-git-send-email-yi.zhu@intel.com>

From: Tomas Winkler <tomas.winkler@intel.com>

This patch fixes endianity issue for frame control field
in iwl_hw_build_tx_cmd_rate function. In addition it converts
frame_ctl to fc to align name convention in driver.
