I've used a USB drive to copy the full sysinfo output off the compuer and attached it to this email.

Please do let me know if there is any more information I can provide that can help

Many thanks,

In my SFP port is an SFP to RJ45 copper module, it is a unbranded generic 10/100/1000Base-T, confirmed to work on Ubuntu.

This card works for me out of the box, with a 10g sfp.
What specific PCI id do you have? what SFP?

This is going to take some debugging.

Quoth Mr Neuralwright <neuralwright@tutamail.com>:
Hi All,
I have recently acquired a 10Gbit PCIE Intel 85299-1SFP network card since this chipset is supported in 9front, although now I suspect the driver may have only RJ45 port variants of 85299 supported, and not SFP - hopefully I'm wrong and I'm just missing something.

#ip/ipconfig
"no success with DHCP*

#ip/ipconfig -g 192.168.1.1 ether /net/ether0 192.168.1.200 255.255.255.0
#ip/ping 192.168.1.1
Pings fail
#cat /net/ether0/adder
successfully returns a MAC address

(Yes, ether0 is the PCIE card and not the integrated NIC)
Notably the Rx/Tx lights on the SFP port do not light up at all. Networking and the activity lights work perfectly fine on Ubuntu out-the-box, so the hardware is fine.

9front does at least recognise the device exists, which is a start. Any suggestions on how to resolve this?
