Due to an inappropriate concept of handling the per-CPU sent packets' processing on TX path the driver numerous problems occured, such as RCU stalls. Those have been fixed, of which details you can find in the commit logs. The patches were intensively tested on top of v4.2-rc5. I'm looking forward to any comments or remarks.
