This same structure will be used to retrieve RX filter info for
interfaces on the host via netlink messages, and RX filter info for

Is there ever a chance these could be different for one of these types?
Seems "excessive" to make 3 specific definitions when 1 generic one
could suffice (drop the "Unicast, Multicast, Vlan")

I haven't peeked ahead yet, but are these tables where the allocation is
allocate space for 10 table entries, allocate entries in each array
entry... If so, then the free will need to run through the tables.
Reason why I ask is I see size_t's for each structure indicating to me
it's a array of entries.

Each of the mode's would just use the generic FilterMode and the
comments adjusted accordingly...
soft ACK with changes depending on future patches which I haven't peeked
at yet.
