a virtual function (VF), jumbo frames must first be enabled in the physical
function (PF). The VF MTU setting cannot be larger than the PF MTU.
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

The driver supports the in-kernel software implementation of GRO. GRO has
