Subject: [PATCH net] bonding: enhance L2 hash helper with packet type

From: Jianhua Xie <jianhua.xie@...escale.com>

Current L2 hash helper calculates destination eth addr and
source ether addr as L2 hash factors. This patch is adding
packet type ID field into hash factors, which can help to
distribute different types of packets like IPv4/IPv6 packets
to different slave devices while only BOND_XMIT_POLICY_LAYER2
is applied.
