Subject: [PATCH] ath9k_hw: remove aggregation protection mode
Date: Tue, 3 May 2011 13:14:06 +0530 [thread overview]
Message-ID: <1304408646-9411-1-git-send-email-mshajakhan@atheros.com> (raw)
From: Mohammed Shafi Shajakhan <mshajakhan@atheros.com>
when aggregation protection mode is enabled the hardware needs
to send RTS/CTS for each HT frame. Currently its disabled so
remove the unused call backs.
