Sorry, I think that was just reading too quickly on my part, I did not notice it was a TX timeout. I don't know how much you are able to experiment on this setup, but it sounds reminiscent of the problems that resulted in the "bufferbloat" work a few years back. A lot of that was maintained out of tree for a while, so depending on how new your kernel and distribution is it may or may not be incorporated already. This is pretty old, not sure how much still applies. Hopefully a lot has been incorporated already, but you may need to tweak for your particular configuration: https://www.bufferbloat.net/projects/bloat/wiki/Linux_Tips/ -- Chris Caudle ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
