Additional info:
Here’s a DPDK patch (”net/i40e/base: fix unknown PHYs incorrect identification”)

that was submitted on 2016-12-10, too late for DPDK 16.11:

    http://dpdk.org/browse/dpdk/commit/drivers/net/i40e/base/i40e_common.c?id=e19e16ad7a39033650057e0d24f55502da4f15d9

 
The description states:


The PHY type value for unrecognized PHYs and cables was changed

based on firmware version number. Newer hardware use lower firmware

version numbers and this was causing some PHYs to be identified

as type 0x16 instead of 0xe (unknown).

 

Without this patch, newer card will incorrectly identify unknown

PHYs and cables.

 

This change adds hardware type to the check for firmware version

so the PHY type is reported correctly.

 

This change does not appear to have been backported to DPDK 16.11.2.
