bonding: Add new layer2+3 hash for xor/802.3ad modes

Browse Source 
Add new hash for balance-xor and 802.3ad modes.  Originally
 submitted by "Glenn Griffin" <ggriffin.kernel@gmail.com>; modified by
 Jay Vosburgh to move setting of hash policy out of line, tweak the
 documentation update and add version update to 3.2.2.

	Glenn's original comment follows:

Included is a patch for a new xmit_hash_policy for the bonding driver
that selects slaves based on MAC and IP information.  This is a middle
ground between what currently exists in the layer2 only policy and the
layer3+4 policy.  This policy strives to be fully 802.3ad compliant by
transmitting every packet of any particular flow over the same link.
As documented the layer3+4 policy is not fully compliant for extreme
cases such as ip fragmentation, so this policy is a nice compromise
for environments that require full compliance but desire more than the
layer2 only policy.
