Subject: [PATCH] net/: fix the WIRELESS_EXT abuse

This patch contains the following changes:
- add a CONFIG_WIRELESS_EXT select'ed by NET_RADIO for conditional
  code
- remove the now no longer required #ifdef CONFIG_NET_RADIO from some
  #include's

Based on a patch by Jean Tourrilhes <jt@hpl.hp.com>.

Subject: [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.
