++NBASE-T Support
++---------------
++The ixgbe driver supports NBASE-T on some devices. However, the advertisement
++of NBASE-T speeds is suppressed by default, to accommodate broken network
++switches which cannot cope with advertised NBASE-T speeds. Use the ethtool
++command to enable advertising NBASE-T speeds on devices which support it::
++
++  ethtool -s eth? advertise 0x1800000001028
++
++On Linux systems with INTERFACES(5), this can be specified as a pre-up command
++in /etc/network/interfaces so that the interface is always brought up with
++NBASE-T support, e.g.::
++
++  iface eth? inet dhcp
++       pre-up ethtool -s eth? advertise 0x1800000001028 || true
++
+ Generic Receive Offload, aka GRO
+ --------------------------------
+ The driver supports the in-kernel software implementation of GRO. GRO has
