Right, but the point I was making is that when I started playing with
ethtool last year, I found that the paramenter autoneg [on|off] *had* to
be the first parameter, otherwise it gagged trying to set other options.
Clearly, it's a dumb program, that just reads the list, and performs them
one at a time, in order of appearance (read, perform, pop parm, repeat)
