[PATCH] bonding: suppress duplicate packets
Originally submitted by Kenzo Iwami; his original description is: The current bonding driver receives duplicate packets when broadcast/ multicast packets are sent by other devices or packets are flooded by the switch. In this patch, new flags are added in priv_flags of net_device structure to let the bonding driver discard duplicate packets in dev.c:skb_bond(). Modified by Jay Vosburgh to change a define name, update some comments, rearrange the new skb_bond() for clarity, clear all bonding priv_flags on slave release, and update the driver version.
