I agree.  Something like:

        ethtool -s ethx auto on advertise mode1+mode2+...+moden

For example:

        ethtool -s ethx auto on advertise 100-half+100-full

to set speed 100 either half or full duplex.

Maybe have some abbreviations such as 100-all (same as above) or
all-half (for all supported half duplex) or just all (for all supported
modes), which I suppose is the default.

Just an idea.
