IB/mlx5: Allow creation of a multi-packet RQ
Allow creation of a multi-packet receive queue. In order to create a multi-packet RQ, the following fields in the mlx5_ib_rwq should be set: - log_num_strides: Log of number of strides per WQE - single_stride_log_num_of_bytes: Log of a single stride size - two_byte_shift_en: When enabled, hardware pads 2 bytes of zeros before writing the message to memory (e.g. for the IP alignment).
