Subject: [RFC 4/6] mac80211: Allow disabling SGI-20.
Date: Wed, 12 Dec 2012 13:54:53 -0800	[thread overview]
Message-ID: <1355349295-30960-4-git-send-email-greearb@candelatech.com> (raw)
In-Reply-To: <1355349295-30960-1-git-send-email-greearb@candelatech.com>

From: Ben Greear <greearb@candelatech.com>

This allows user-space (wpa_supplicant) to disable
short guard interval (SGI) for 20Mhz.  The SGI-40
disable option is already handled.
