TNSR interface link speed

stivi

Hi all,
After installing TNSR 22.10-2, I can't force the link speed 2.5G on the interfaces. I have tried using ethtool (sudo ethtool -s vpp2 speed 2500 duplex full autoneg off) but after the change nothing happened. I searched the documentation for dpdk, but found nothing.
I have an Intel X550 T2, and I have checked on pfsense that this card work well on 2.5G.

@stivi I have found this:
https://doc.dpdk.org/guides-21.05/rel_notes/release_21_05.html
"Added a command line option to configure forced speed for an Ethernet port: dpdk-testpmd -- --eth-link-speed N."
Is this possible in tnsr?
