The assumption that the channel is only opened upon synthetic device attach time no longer holds, e.g. Hyper-V network device MTU changes.

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.
