The HCA declares the maximum message size it is capable of
transmitting through query dev cap. When modifying a QP we
should set this value. For connected QPs where messages sizes can be
quite large we should set this value to a value not larger then the
value published. So this patch sets it to the maximum allowed value.

I can't say this patch is urgent but I sent a few months ago and we do
wish to see it in the upstream kernel after being reviewed. Based on
that, let me know if you think we should push it and I can add more
information to the changelog.
