* hyperv/vmbus: Fix sub-channel re-open support.Sepherosa Ziehau2016-07-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | For multi-channel devices, once the primary channel is closed, a set of 'rescind' messages for sub-channels will be delivered by Hypervisor. Sub-channel MUST be freed according to these 'rescind' messages; directly re-openning sub-channels in the same fashion as the primary channel's re-opening does NOT work at all. After the primary channel is re-opened, requested # of sub- channels will be delivered though 'channel offer' messages, and this set of newly offered channels can be opened along side with the primary channel. This unbreaks the MTU setting for hn(4), which requires re- openning all existsing channels upon MTU change.
