Date: Thu, 12 Apr 2012 09:32:52 -0700 Message-Id: <1334248375-22967-3-git-send-email-greearb@candelatech.com> (sfid-20120412_183352_601421_B7B7C2EA) In-Reply-To: <1334248375-22967-1-git-send-email-greearb@candelatech.com> References: <1334248375-22967-1-git-send-email-greearb@candelatech.com> Sender: linux-wireless-owner@vger.kernel.org List-ID: From: Ben Greear This lets ethtool print out stats related to stations connected to the interface. Does not yet get stats from the underlying driver. Signed-off-by: Ben Greear --- :100644 100644 3557354... 420b6eb...
