Since now when bonding uses rx_handler, all traffic going into bond device goes thru bond_handle_frame. So there's no need to go back into bonding code later via ptype handlers. This patch converts original ptype handlers into "bonding receive probes". These functions are called from bond_handle_frame and they are registered per-mode. Note that vlan packets are also handled because they are always untagged thanks to vlan_untag() Note that this also allows arpmon for eth-bond-bridge-vlan topology.
