From d2a5128fbc30480763bbb8a43ec7c8161c1bf055 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Fri, 30 Aug 2013 16:49:27 -0500 Subject: [PATCH] net: calxedaxgmac: remove some unused statistic counters rx_sa_filter_fail and tx_undeflow events are unused and impossible to occur based on how the h/w is used. We never filter on source MAC address and TX store and forward mode prevents underflow events. Reported-by: Lennert Buytenhek Signed-off-by: Rob Herring Signed-off-by: David S.
