    Subjectwhen using arp monitoring with bonding, why use broadcast arps?

    We have a network with a number of nodes using bonding with arp
    monitoring. The arp interval is set to 100ms.

    Unfortunately, the bonding code sends the arp packets to the hardware
    broadcast address, which means that the number of these arp packets seen
    by each node goes up with the number of nodes on the network.

    One of the nodes has a fairly low-powered cpu and handles most things in
    microengine code, but arp packets get handled in software. All these
    broadcast arps slow this node down noticeably.

    Is there any particular reason why the bonding code couldn't use unicast
    arp packets if the "arp_ip_target" has a valid entry in the sender's arp
    table?

    Thanks,

    Chris
