That depends.  What's the effect of this bug?  Is it something that
should be sent to stable?  If the common case is that the send and recv
cq sizes are the same, and this bug is mostly never an issue, then no,
no v2 is necessary.  If this is something we should send to stable, then
yes, pull out the bugfix, tag it for stable, and submit v2.
