This is already broken for large numbers of VFs, and increasing the
amount of information per VF is going to make the situation worse. I am
no netlink expert but I think that the current approach of bundling all
information about an interface in a single message may not be
sustainable.
Also, I'm unclear on why this interface is to be used to set filtering
for the (PF) net device as well as for related VFs. Doesn't that
duplicate the functionality of ndo_set_rx_mode and
ndo_vlan_rx_{add,kill}_vid?
