From 3dab99e0b37e16525949757f46e33fb9612c73ec Mon Sep 17 00:00:00 2001 From: Vince Bridgers Date: Thu, 9 Oct 2014 10:10:36 -0500 Subject: [PATCH] stmmac: correct mc_filter local variable in set_filter and set_mac_addr call Testing revealed that the local variable mc_filter was dimensioned incorrectly for all possible configurations and get_mac_addr should have been set_mac_addr (a typo). Make sure mc_filter is dimensioned to 8 32-bit unsigned longs - the largest size of the Synopsys multicast filter register set.
