Merge branch 'bonding-fix-high-prio-not-effect-issue'
Hangbin Liu says:
====================
Bonding: fix high prio not effect issue
When a high prio link up, if there has current link, it will not do
failover as we missed the check in link up event. Fix it in this patchset
and add a prio option test case.
