Chelsio is the only iWARP driver in ofed-1.2.x.  ofed-1.3 has NetEffect 
too.  Dunno if they support SDP.

If you go up to 1.2.5.4 or ofed-1.3-rc1 and try out SDP over chelsio, 
I'll help ya debug stuff as time permits.

They should be.  Its just that there are a few dozen bug fixes from 1.2 
to 1.2.5.4 in the chelsio drivers.  Also, if you go up to 1.2.5.4, 
you'll need the 5.0 firmware from cheslio's web site.  Pull down the 
firmware and put it in /lib/firmware.  Then it should get upgraded 
automagically.
