Just asking so that work is not duplicated. I'm willing to produce the patches, although 1) I don't currently have a platform set up to test whether they compile; 2) I don't have hardware on which to test whether they work (the person who submitted https://github.com/the-tcpdump-group/tcpdump/issues/393#issuecomment-218442072 does, although he doesn't have X550 hardware - I guess he wants hardware time stamping on an 82599EB; it sounds as if that won't work, and his patch to the driver won't give him what he wants); 3) patches from the driver maintainers might 1) be more likely to do the right thing and 2) be more likely to be accepted.
