Logically speaking, this patch pertains to the "Fix issues in tc-taprio and tc-cbs" series at: https://patchwork.ozlabs.org/project/netdev/list/?series=127821&state=*
The reason why I did not submit this patch together with those is that I don't know whether the error condition can happen in current mainline Linux at the moment. I am running Arseny's RFC patch "gianfar: convert to phylink" and have found that __ethtool_get_link_ksettings returns a speed of 0 instead of SPEED_UNKNOWN when there is no PHY connected. Gianfar has carried this oddity over from its PHYLIB days, where it connects "late" to the PHY. I am not sure whether PHYLINK, gianfar, or both, need to be changed. Comments welcome.
