Failing to create a QP makes me wonder if you have have this patch?

 Subject: [PATCH v2 1/2] RDMA/uverbs: Fix the check for port number

 The port number is only valid if IB_QP_PORT is set in the mask.
 So only check port number if it is valid to prevent modify_qp from
 failing due to an invalid port number.

 Fixes: 5ecce4c9b17b("Check port number supplied by user verbs cmds")
