[PATCH 2.6.13-rc1 15/17] bonding: include ARP and Xmit Hash Policy information in /proc file

[Radheka Godse <radheka.godse@intel.com>]

For bonds configured to do ARP monitoring, this patch displays polling 
interval and ip targets info in their respective proc files.

For balance-XOR and 802.3ad modes, this patch displays Xmit Hash Policy.
