I'm not sure it is necessary to change the existing e1000g.conf
configuration, if we define the precedence of dladm config vs e1000g.conf
clearly and have the mac_get_prop* functions use the correct
search order. I would propose that we should prefer dladm config over 
driver.conf so that users who knowingly type a "dladm set-linkprop -p mtu.."
command will have that choice have higher precedence over 
the (harder to use) e1000g.conf settings. And if they already have
some legacy settings in e1000g.conf, those settings will continue to work.

Comments?
