I think I tried it and it did not work, but I shall try again. Where should I put it ? in init.d startup scripts ? I think I tried, and yet , I have seen that in reset, the leds of the phy are always turned off for a ~1.5 second and then on again. This is actually what I am trying to overcome, this strange reset of phy every powerup. > You could refer to something like this for more information: > https://www.shellhacks.com/change-speed-duplex-ethernet-card-linux/ > > Thanks. > > - Alex Thank you very much, ran ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ E1000-devel mailing list E1000-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/e1000-devel To learn more about Intel® Ethernet, visit http://communities.intel.com/community/wired
