Instead of trying to disable it in the driver why not just change your system configuration to disable it? You should be able to configure things in either Network Manager, or via the network init scripts so that you instead just used a forced speed/duplex combination. If nothing else you can go through and drop support for any other advertised speed/duplex and that should improve the speed of autoneg itself. You could refer to something like this for more information: https://www.shellhacks.com/change-speed-duplex-ethernet-card-linux/ Thanks. - Alex ------------------------------------------------------------------------------ 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
