This patch adds support for allocating, configuring, and freeing Tx/Rx ring
resources. With these changes in place the descriptor queues are in a
state where they are ready to transmit or receive if provided buffers.
This also adds the transmit and receive fastpath and interr

This patch adds the basic defines and structures needed by the PF for
operation. With this it is possible to bring up the interface,
but without being able to configure any of the filters on
the interface itself.

This series adds support for the new igc driver.
The igc driver is the new client driver supporting the Intel I225
Ethernet Controller, which supports 2.5GbE speeds. The reason for
creating a new client driver, instead of adding support for the new
device in e1000e, is that the silicon behaves mo

Regarding the chip version the dmesg line with the XID would be relevant.
4.18.15 + PDS (custom CPU scheduler) + cherry pickings from mainline.
