net: arc_emac: don't pass multicast packets to kernel in non-multicast mode
The patch disable capturing multicast packets when multicast mode disabled for ethernet ('ifconfig eth0 -multicast'). In that case no multicast packet will be passed to kernel. Signed-off-by: Alexander Kochetkov <al.kochet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
