We won't be accepting this patch for the following reasons: The default has been changed but you will be able to enable those speeds using ethtool now. The default of 2.5G and 5G are OFF because of interoperability issues with certain 10G switches that are confused by 2.5G and 5G and negotiate down to 1G.
The README is still in error and says ethtool can't change the advertisement of 2.5G and 5G, but that should be fixed in the next version. You should be able to just use ethtool with the mask shown in the man page. We did consider your case of users with 2.5G and 5G networks, but the throttling of 10G to 1G was seen as a much larger issue which we saw repeatedly in large data centers. Thanks.

I enclose a simple change to the *ixgbe_setup_phy_link_speed_generic* function that fixes the issue. Note that the Windows drivers support these speeds out of the box. _______________________________________________ E1000-devel mailing list E1000-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/e1000-devel To learn more about Intel Ethernet, visit https://forums.intel.com/s/topic/0TO0P00000018NbWAI/intel-ethernet
