From reading the balance-alb description, I get the impression that this
mode is simply not meant to be used with bridging:
Adaptive load balancing: includes balance-tlb plus
receive load balancing (rlb) for IPV4 traffic, and
does not require any special switch support. The
receive load balancing is achieved by ARP negotiation.
The bonding driver intercepts the ARP Replies sent by
the local system on their way out and overwrites the
source hardware address with the unique hardware
address of one of the slaves in the bond such that
different peers use different hardware addresses for
the server.
In any case I'd tend to say that if bond-alb mode mangles outgoing MAC
addresses, it should restore the original one for received packets
and keep the hacks local to bonding.
