Bruce Allan 0c6bdb3084 e1000e: avoid polling h/w registers during link negotiation
Avoid touching hardware registers when possible, otherwise link negotiation
can get messed up when user-level scripts are rapidly polling the driver to
see if/when link is up.  Use the saved link state information instead when
possible.
