CQ Tang	4668e4b527	IB/qib: Improve SDMA performance 1. The code accepts chunks of messages, and splits the chunk into packets when converting packets into sdma queue entries. Adjacent packets will use user buffer pages smartly to avoid pinning the same page multiple times. 2. Instead of discarding all the work when SDMA queue is full, the work is saved in a pending queue. Whenever there are enough SDMA queue free entries, pending queue is directly put onto SDMA queue. 3. An interrupt handler is used to progress this pending queue.
