Subject: [net-next 8/9] i40e: fix link reporting

From: Alan Brady <alan.brady@...el.com>

When querying the NVM for supported phy_types, on some firmware
versions, we were failing to actually fill out the phy_types which means
ethtool wouldn't report any link types.

Testing-hints:
Check 'ethtool <iface>' if you have the right (wrong?) firmware.
Without this patch, no link modes will be reported.
