[ofw] SRQ attached qp creation fails for connectX and OK for Infinihost?

[Smith, Stan]

Hello,
  Can you think of a reason why IPoIB-CM code that creates a receive QP [create_qp()] which references a SRQ (create_qp.h_srq = shared_rx_queue_qp_h) would always succeed when run over an Infinihost HCA, while the very same code always fails when run over a ConnectX HCA?
Same win2kR2 x64 OS base, same hardware platform except different HCAs; A single HCA per system.

The failing create_qp() return code is IB_INVALID_PARAMETER.

First and subsequent create_qp() calls always fail for ConnectX (MT26418, firmware 2.7.0)?
All QP parameters are far less than supported CA maximums.

Again, the very same code/driver/bits works fine for Infinihost MT25208 and fails on MT26418.

Any ideas?

thanks,

stan.
