Subject: [PATCH 14/25] iwlwifi: move iwl4965_set_rxon_ht into iwlcore
Date: Mon,  5 May 2008 10:22:41 +0800	[thread overview]
Message-ID: <1209954172-3092-15-git-send-email-yi.zhu@intel.com> (raw)
In-Reply-To: <1209954172-3092-14-git-send-email-yi.zhu@intel.com>

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

This patch moves iwl4965_set_rxon_ht to iwlcore under name
iwl_set_rxon_ht. It also moves collateral changes
iwl_is_channel_extension and iwl_is_fat_tx_allowed.
