From e71c9ce262269ed12d042ea56da63a51c97fd880 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Tue, 17 Apr 2018 23:28:28 +0200 Subject: [PATCH] r8169: change argument type of counters handling functions The counter handling functions don't deal with the net_device, so code can be simplified by changing the argument type to struct rtl8169_private *.
