RDMA/mlx5: Add support for rate limit in UD and UC QPs

Browse source

Rate limiting is currently supported only for raw packet QPs, where
the packet pacing index is programmed into the SQC during SQ modify.

Extend rate limit support to UD and UC QPs by setting the pacing
index in the QPC during RTR2RTS and RTS2RTS transitions.
