Subject: [PATCH] brcmfmac: Use net_device_stats from struct net_device
Date: Mon, 13 Feb 2017 11:14:09 +0100	[thread overview]
Message-ID: <20170213101409.8205-1-tklauser@distanz.ch> (raw)

Instead of using a private copy of struct net_device_stats in struct
brcm_if, use stats from struct net_device.  Also remove the now
unnecessary .ndo_get_stats function.
