Hi Misc,
I have 2 questions about my dual port fiber optic ethernet card with Intel
I210 chipset:
1. The ifconfig em0 media command output only shows that it supports
multi-mode fiber (1G SX).
Actually it worked when I tried single mode fiber. But I still wanted to
report this to OpenBSD developers.
2. The ifconfig em0 sff or ifconfig em0 transceiver output does not return
information about transceiver.
Could the EM driver not support the transceiver / sff command set?
I searched on Google but I couldn't find such an expression.
You can find the relevant command outputs below.
Thank you very much for your help in advance.
Stay safe.
