====================
Bonding: add per-port priority support

This patch set add per-port priority for bonding failover re-selection.

The first patch add a new filed for bond_opt_value so we can set slave
value easier. I will update the bond_option_queue_id_set() setting
in later patch.

The second patch add the per-port priority for bonding. I defined
it as s32 to compatible with team prio option, which also use a s32
value.

v3: store slave_dev in bond_opt_value directly to simplify setting
    values for slave.

v2: using the extant bonding options management stuff instead setting
    slave prio in bond_slave_changelink() directly.
