Title:
i40e NIC not recognized
Status in linux package in Ubuntu:
Incomplete
Status in linux source package in Trusty:
New
Bug description:
== 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.
