ethtool SFP+ with Dell VEP4600/SD-WAN Edge 3000 x722 ports

Hi,

could somebody help confirm if ethtool from upstream Linux can query SFP+ information with the x722?

I get information on the rNDC ports, but not the builtin ports.

rNDC:

flo-dellveptest# ethtool --module-info eth8 | grep Vendor
        Vendor name                               : Intel Corp
        Vendor OUI                                : 00:1b:21
        Vendor PN                                 : AFBR-709DMZ-IN2
        Vendor rev                                : G4.1
        Vendor SN                                 : AD180730FX7

Whereas on the 'main' ports of the system on the x722 NIC, I don't get anything :-(

flo-dellveptest# ethtool --module-info eth9 | grep Vendor
netlink error: Invalid argument
flo-dellveptest# ethtool --module-info eth10 | grep Vendor
netlink error: Invalid argument

I got ethtool version 6.1, the firmwares are as they should be (x722 onboard supposedly can't upgrade above 6.20).

flo-dellveptest# ethtool -i eth8
driver: i40e
version: 5.15.152-0-lts
firmware-version: 9.20 0x8000d969 22.0.9

supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: yes
flo-dellveptest:~# ethtool -i eth9

kernel is a matching 5.15.152-0-lts

I'm uncertain where the limitation is (upstream ethtool, upstream drivers, correct firmware, and working for the 710 card...)
