Hi,
I’m running VyOS on a router with a Intel x553 NIC that uses the ixgbe driver.
Inserting some generic optics generates an error:
[3355357.146524] ixgbe 0000:07:00.0: failed to initialize because an unsupported SFP+ module type was detected.
[3355357.154859] ixgbe 0000:07:00.0: Reload the driver after installing a supported module.
[3355357.167141] ixgbe 0000:07:00.0: removed PHC on eth1
There’s an option in the driver (options ixgbe allow_unsupported_sfp=1) to support unsupported SFP+ modules as described here: How to enable unsupported SFP+
However sudo update-initramfs -u still doesn’t work.
How can we enable this option in VyOS?
As I recall it there is a difference regarding this between the in-tree and out-of-tree intel driver.
What about do you get from:
modinfo ixgbe | grep -i intree
Also according to this:

VyOS should default to have that flag enabled aka supporting 3rd party transceivers on intel drivers.
And according to:
and:
it do seems like the out-of-tree driver is being used:
