Subject: [PATCH] bonding: Inactive slaves should keep inactive flag's value to 1.

Except bond mode 1, in other bond modes, inactive slaves should keep inactive flag to
1 to refuse to receive broadcast packets. Now, active slave send broadcast packets
(for example ARP requests) which will arrive inactive slaves on same host from switch,
but inactive slave's inactive flag is zero that cause bridge receive the broadcast
packets to produce a wrong entry in forward table. Typical situation is domu send some
ARP request which go out from dom0 bond's active slave, then the ARP broadcast request
packets go back to inactive slave from switch, because the inactive slave's inactive
flag is zero, kernel will receive the packets and pass them to bridge, that cause dom0's
bridge map domu's MAC address to port of bond, bridge should map domu's MAC to port of vif.
