[openib-general] 3513 DAPL is Broken

[Woodruff, Robert J]

Seems to hang around the time of the modify QP.

ibv_rc_pingpong seems to work OK and also your 
DAPL-socket CM version that you gave me yesterday seems 
to work, but the DAPL I pulled from SVN that uses the IB AT/CM
has the following problem. 

I am starting to think that pushing out your socket CM
version until things stabilize with the IBAT/IBCM version
might be worth considering, so that people that
want to use DAPL now have something that is reliable.
