net: stmmac: xgmac: fix missing IFF_MULTICAST checki in dwxgmac2_set_filter
Without checking for IFF_MULTICAST flag, it is wrong to assume multicast filtering is always enabled. By checking against IFF_MULTICAST, now the driver behaves correctly when the multicast support is toggled by below command:- ip link set <devname> multicast off|on Fixes: 0efedbf11f07a ("net: stmmac: xgmac: Fix XGMAC selftests") Signed-off-by: Tan, Tee Min <tee.min.tan@intel.com> Signed-off-by: Ong Boon Leong <boon.leong.ong@intel.com> Signed-off-by: David S.
