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

and hardware timestamping is not possible (SKBTX_IN_PROGRESS not set).
- As soon as the driver has sent the packet and/or obtained a
hardware time stamp for it, it passes the time stamp back by
calling skb_hwtstamp_tx() with the original skb, the raw
hardware time stamp. skb_hwtstamp_tx() clones the original skb and
calling skb_tstamp_tx() with the original skb, the raw
hardware time stamp. skb_tstamp_tx() clones the original skb and
adds the timestamps, therefore the original skb has to be freed now.
If obtaining the hardware time stamp somehow fails, then the driver
should not fall back to software time stamping. The rationale is that
