[PATCH] bonding: documentation update

Contains general updates (additional configuration info, hopefully
better examples, updated some out of date info, and a bonus pass
through ispell to banish the "paramters.") and info specific to
gratuitous ARP and xmit policy functionality already in 2.6.13-rc2.
