I gone through Linux network stack and didn't find a way where stack asks the driver to add mcast address for vlan interfaces. *_Network Experts_* can help us here. > 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 For now this is the only possible option that can be used.
