Add logic to check ARP request / reply packets used for ARP
monitor link integrity checking.
The current method simply examines the slave device to see if it
has sent and received traffic; this can be fooled by extraneous traffic.
For example, if multiple hosts running bonding are behind a common
switch, the probe traffic from the multiple instances of bonding will
update the tx/rx times on each other's slave devices.

Add priv_flag to specifically identify bonding-involved devices. Needed
because IFF_MASTER is an unreliable identifier (vlan interfaces above bonding
will inherit IFF_MASTER). Misidentification of devices would cause
notifier events for other devices to be erroneously processed by bonding,
causing various havoc.

Fix a problem where NetLabel would always set the value of
sk_security_struct->peer_sid in selinux_netlbl_sock_graft() to the context of
the socket, causing problems when users would query the context of the
connection. This patch fixes this so that the value in
sk_security_struct->peer_sid is only set when the connection is NetLabel based,
otherwise the value is untouched.

This is version 21 of the Wireless Extensions. Changelog :
o finishes migrating the ESSID API (remove the +1)
o netdev->get_wireless_stats is no more
o long/short retry
This is a redacted version of a patch originally submitted by Jean
Tourrilhes. I removed most of the additions, in order to minimize
future support requirements for nl80211 (or other WE successor).
