Subject: Re: [PATCH net-next] net: sfp: add quirk for OEM DFP-34X-2C2 GPON
ONU SFP
Hi Sergio,
I did ask for the kernel messages from a specific scenario:
- host that supports 1000base-X and 2500base-X with your quirk
- SFP inserted with LAN_SDS_MODE=1
What I expet to see in the kernel messages is that the system will
use 2500base-X, and a failure.
You claim that the kernel will link at 1000base-X. There is no
mechanism in the kernel for this to happen, and I believe that
if you look at the kernel messages, this will prove my point.
