Hello, Looking at the code in virtnet_set_link_ksettings, it seems the speed and duplex can be set to any valid value. The driver will "remember" them and report them back in virtnet_get_link_ksettings. However, the supported link modes (link_modes.supported in struct ethtool_link_ksettings) is always 0, indicating that no speed/duplex setting is supported. Does it make more sense to set (at least a few of) the supported link modes, such as 10baseT_Half ... 10000baseT_Full? I would expect to see consistency between what is reported in link_modes.supported and what can actually be set. Could you please share your opinion on this? Thank you, Radu Rendec _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
