Hi there,

It seems that for reasons unknown to me, my Intel X533 based 10G SFP+ doesn't want to work with kernel 6.1.55 in VyOS 1.4 nor Debian 12 but it does in OPNsense which is based on FreeBSD 13.2.

How would I go about debugging this properly? Both sides see light, but no link unless I'm using FreeBSD.

have you tried setting the allow_unsupported_sfp=1 module parameter?
parm: allow_unsupported_sfp:Allow unsupported and untested SFP+ modules on 82599-based adapters (bool)

For reference the thread on VyOS forums regarding this: https://forum.vyos.io/t/10g-sfp-trouble-with-linking-intel-x553/12253

Also, for troubleshooting it would be useful to have the output of ethtool -m eth0 from your device.
