x722-da4 unable to set speed via 'ethtool'

[olebenny]

Hello community

I am using 2 x x722-da4 in my 'servers'.

1.

If I connect 2 of these servers back to back with fiber-cables, I get links on all channels at 1 Gb.

If I try to:

ethtool -s ens1f2 speed 10000 duplex full autoneg off

responds:

netlink error: link settings update failed
netlink error: Operation not supported

2.

If I unplug one of the SPFs and put it back in, the speed is now changed to 10Gb

3.

[root@localhost ~]# ethtool -a ens1f2
Pause parameters for ens1f2:
Autonegotiate: off
RX: off
TX: off

4.

[root@localhost ~]# ethtool -i ens1f2
driver: i40e

firmware-version: 5.40 0x80002e40 1.2992.0

Hello olebenny,

Thank you so much for waiting for our update. Please be reminded that base on PCN, the X722-DA4 successor is E810XXVDA4 or Intel® Ethernet Network Adapter E810-XXVDA4. This card works with multi-rate modules. Base on Ark, it has a Data Rate Per Port of 25/10/1GbE.

We also recommend to use modules based on our compatibility tool.

The X710-DA2 is also a possible replacement. However this does not support iWARP functionality.
