NetBSD 9.3 on Cobalt Qube 2 – I/O error after network config change

[Andreas Fankhänel <af.ankhaenel%t-online.de@localhost>]

Hello NetBSD port-mips team,

I am running NetBSD 9.3 on a Cobalt Qube 2, and after modifying the network configuration, I can no longer access the network setup through the rear panel interface.

Steps I followed:
- Executed `select network` in the console
- Pressed Enter
- Received an I/O error message

Could you please advise how to restore access to the network configuration panel? Any guidance on troubleshooting this I/O error would be greatly appreciated.

Thank you very much for your help.

Best regards,
Andreas Fankhaenel
