Thanks for replying to mail. I have a some basic understanding of IB. I
have gone through some of the example code in the example directory and
OFED performance test. I noticed that every one of those examples used
TCP to exchange information regarding lid, psn and qpn. My question is
basically that is there any other way to exchange this information using
only IB. Since no hardware supports RD, I have to bite the bullet and
use RC.
Thanks,
Bharath
