bonding: Support macvlans on top of tlb/rlb mode bonds
To make TLB mode work, the patch allows learning packets
to be sent using mac addresses assigned to macvlan devices,
also taking into an account vlans that may be between the
bond and macvlan device.
To make RLB work, all we have to do is accept ARP packets
for addresses added to the bond dev->uc list. Since RLB
mode will take care to update the peers directly with
correct mac addresses, learning packets for these addresses
do not have be send to switch.
