From: Larry Finger Date: Mon, 11 Jun 2007 00:57:33 +0000 (-0700) Subject: [MAC80211]: Add support for SIOCGIWRATE ioctl X-Git-Tag: firefly_0821_release~28305^2~170 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=b3d88ad49a0623d09efcf998beb26288c8029f75;p=firefly-linux-kernel-4.4.55.git [MAC80211]: Add support for SIOCGIWRATE ioctl At present, transmission rate information for mac80211 is available only if verbose debugging is turned on, and then only in the logs. This patch implements the SIOCGIWRATE ioctl, which adds the current transmission rate to the output of iwconfig. Signed-off-by: Larry Finger Signed-off-by: John W. Linville Signed-off-by: David S.
