Subject: i40e: Add dual speed module support
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=124ed15bf126b5bf437c8eee2873ecbeef464146;p=linux-beck.git

i40e: Add dual speed module support

Now that fw has implemented dual speed module support, we can add ours.
Also, add the phy type for 1G LR/SR and set its media type to fiber.
Lastly, instead of a WARN_ON if the phy type is not recognized just print
a warning.
