Mellenox ConnectX3-Pro and Ubuntu 24 Arista 7050TX-72Q switch

Trying to install Firmware update on a Mellenox ConnectX3-Pro with Ubuntu 24. Can’t install the mft pcap. I want to connect it at 40gbps to an Arista 7050TX-72Q switch.
I just want to connect 40gpbs. Or do I need configure the switch? The 10gbps is work just fine.

what do you get with
#ethtool -m enp1s0f1np1

with Ubuntu it’s just

apt install mstflint

#mstconfig -d 01:00.0 q
