As I understand, when cpsw receive the mcast packet with dst_address=01:00:5e:03:1d:47 and vid=100 it hits the case: "if (Multicast packet) # destination address not found then portmask is the logical “AND” of unreg_mcast_flood_mask and vlan_member_list then goto Egress process" and as result packet is dropped (you can check eth1 statistic # ethtool -S eth1). Unfortunately, I was no able to configure mcast address properly in dual mac mode :(, but probably Mugunthan can comment here - mcast addressess are offloaded to cpsw from Net core through .ndo_set_rx_mode() and struct netdev_hw_addr doesn't contain any information about vlan and cpsw uses default port vlan, which is vid=2 for eth1 in dual mac mode. As W/A the allmulti flag can be used: # ifconfig eth1.100 allmulti -- regards, -grygorii
