Okay, the old vyatta-bonding.pl executed the following code when a bond member has been removed:

sub if_up {
    my $intf = shift;
    system "sudo ip link set dev $intf up"
      and die "Could not set $intf up ($!)\n";

    my $smp_affinity = get_irq_affinity($intf);
    if ($smp_affinity) {
	system "/opt/vyatta/sbin/irq-affinity.pl $intf $smp_affinity"
	    and warn "Could not set $intf smp-affinity $smp_affinity\n";
    }
}

This code is definately not yet migrated!
