Hi Marc and everyone, this is the second part now. I know it is the merge window right now but I am quite sure this won't be merged immediately anyways, so if you have some time for some comments I would appreciate it. So it is still based on v6.1-rc8 + the patches that got applied. I tried to do as small patches as possible so it is easier to understand. The series changed a lot compared to v1 I sent so I didn't call it v2. There are a lot of new patches as well. The series contains a few small fixes and optimizations at the beginning, then adding coalescing support and at the end removing the restrictions on the number of parallel transmits in flight. Note that the last patch 'Implement transmit submission coalescing' does not perform well for me in a loopback testing setup. However I think it may work well in normal testcases. I attached this mechanism to the tx-frames coalescing option, let me know if this is the correct option.
