Jack Morgenstein f36e1793e2 IB/umad: Add support for large RMPP transfers ... Add support for sending and receiving large RMPP transfers. The old code supports transfers only as large as a single contiguous kernel memory allocation. This patch uses linked list of memory buffers when sending and receiving data to avoid needing contiguous pages for larger transfers. Receive side: copy the arriving MADs in chunks instead of coalescing to one large buffer in kernel space. Send side: split a multipacket MAD buffer to a list of segments, (multipacket_list) and send these using a gather list of size 2. Also, save pointer to last sent segment, and retrieve requested segments by walking list starting at last sent segment. Finally, save pointer to last-acked segment. When retrying, retrieve segments for resending relative to this pointer. When updating last ack, start at this pointer.
