[SRU][Trusty][PATCH 0/6] i40e NIC not recognized (LP: #1789215)

[Juerg Haefliger]

This patch series adds Xenial's i40e driver as an additional Ubuntu-specific
i40e_bpo driver to Trusty. A compatibility layer has been added so that it
compiles for Trusty's 3.13 kernel. The driver has also been modified to only
recognize devices that the 3.13 in-tree driver doesn't support to prevent
introducing a regression.

Successfully tested on real HW.

== SRU Justification ==

Booting Trusty with kernel 3.13.0-156-generic on a fairly new Intel box with a
i40e NIC results in no network. The 3.13 i40e driver doesn't support the
following HW:

3d:00.0 Ethernet controller: Intel Corporation Device 37d2 (rev 02)
        Subsystem: Intel Corporation Device 35ce
        Flags: bus master, fast devsel, latency 0, IRQ 37
        Memory at ac000000 (64-bit, prefetchable) [size=16M]
        Memory at ad808000 (64-bit, prefetchable) [size=32K]
        Expansion ROM at ad980000 [disabled] [size=512K]
        Capabilities: <access denied>

Base Board Information
        Manufacturer: Intel Corporation
        Product Name: S2600WFT

This is a Canonical test system and having functional networking with a Trusty
kernel would help with - well - testing :-)

== Fix ==

Add a backport driver in addition to the in-tree driver that supports newer
versions of the i40e NIC.

== Regression Potential ==

Low. The new driver will only load for NICs that are not supported by the
current in-tree driver.

== Test Case ==

Boot a patched kernel and verify the NIC is recognized and the network
comes up.
