So, identical ethtool output unless I'm missing something?
Maybe responsible: There are two NICs on the same subnet as not to get
locked out. Some OSs tolerate this while some do not. Because "dhclient"
addressing works fine, I trust that is okay but the plan is to next try
it without the 1GbE interface connected.
Other ideas?
In short, 'dhclient <interface>' gives a solid 10GbE. DHCP via
network-scripts drops to 1GbE.
