IB/hfi1: Add functions to transmit datagram ipoib packets
This patch implements the mechanism to accelerate the transmit side of a multiple transmit queue RDMA netdev by submitting the packets to the SDMA engine directly instead of sending through the verbs layer. This patch also changes the UD/SEND_ONLY op to output the entropy value in byte 0 of deth[1]. UD/SEND_ONLY_WITH_IMMEDIATE uses the previous behavior with no entropy value being output. The code in the ipoib rdma netdev which submits tx requests upon successful submission will call trace_sdma_output_ibhdr to output the ibhdr to the trace buffer.
