[ Upstream commit 36b20fcdd9663ced36d3aef96f0eff8eb79de4b8 ]
When MC (multicast) list is updated by the networking layer due to a user command and as well as when allmulti flag is set, it needs to be passed to the enslaved Ethernet devices. This patch allows this to happen by implementing ndo_change_rx_flags() and ndo_set_rx_mode() API calls that in turns pass it to the slave devices using existing API calls.
