bonding: Rework / fix multiple gratuitous ARP support
Support for sending multiple gratuitous ARPs during failovers
was added by commit:
commit 7893b2491a2d5f716540ac5643d78d37a7f6628b
Author: Moni Shoua <monis@voltaire.com>

bonding: Send more than one gratuitous ARP when slave takes over
This change modifies that support to remove duplicated code,
add support for ARP monitor (the original only supported miimon), clear
the grat ARP counter in bond_close (lest a later "ifconfig up" immediately
start spewing ARPs), and add documentation for the module parameter.
Also updated driver version to 3.3.0.
