Hi,

Setting media type on 82599ES (and other HW supported by ixgbe) is implemen=
ted
by limiting list of advertised speeds to single value and restarting
auto-negotiation. This is the way HW works - see Datasheet chapter 3.7.4.2 =
MAC
Link Setup and Auto-Negotiation for details. I'm not sure if showing 'Ether=
net
autoselect' should be considered as a bug in this case.
