netlink for ethtool came up at netconf/netdev and we had promised to
send some of the ethtool netlink code we have.
We use a generic netlink channel for ethtool between our kernel and
user space driver. This ethtool channel nicely wraps most ethtool
commands into genl messages.

This patch does two things.
First it allows TCP to aggregate TCP frames with a fixed IPv4 ID field. As
a result we should now be able to aggregate flows that were converted from
IPv6 to IPv4. In addition this allows us more flexibility for future
implementations of segmentation as we may be able
This patch adds support for something I am referring to as GSO partial.
The basic idea is that we can support a broader range of devices for
segmentation if we use fixed outer headers and have the hardware only
really deal with segmenting the inner header. The idea behind the naming
is due to the

The strings were missing for several of the GSO offloads that are

When we have the ISS.CGIS bit set, we already know that gPTP interrupt has
happened, so an extra GIS register check at the end of ravb_ptp_interrupt()
seems superfluous. We can model the gPTP interrupt handler like all other
dedicated interrupt handlers in the driver and make it *void*.

This is also very interesting for storage targets, which face the same

which is probably very similar to what NICs want to do.
