There's a new transmit hash policy being added to the bonding driver that
is a simple XOR of vlan ID and source MAC, xmit_hash_policy vlan+srcmac.
This trivial patch makes it configurable and queryable via iproute2.

$ sudo modprobe bonding mode=2 max_bonds=1 xmit_hash_policy=0

$ sudo ip link set bond0 type bond xmit_hash_policy vlan+srcmac

$ ip -d link show bond0
