Will GPON Nokia G-010S-A change sn?

Hardware Questions and Recommendations

My objective is to run this OpenWRT module in LAN mode at 2500Mbps on OPNsense or pfSense. I'm more familiar with Linux(Debian 10.5.0), so I thought I'd try it out on this platform first, especially after seeing these excellent instructions.

I learned from the post that only limited number of switches (Ubiquiti US-XG-6POE, ES-16-XG, US-16-XG) or Broadcom BCM57810S network card support 2.5G on SFP+ for fiber modules. The Broadcom card require some digging in diagnostic mode to enable 2.5G mode.
First step behind. Port 1 enabled for 2.5G. I left Port 2 unchanged in 1G/10G mode.

The second step calls for a little soldering. It's much easier to do it on a network card (sorry, I couldn't resist, not to post this great picture)

or the G-010S-A module itself. Much harder to do. More info at this blog post.

Ethtool has discovered a new link mode

root@debianBCM:~# ethtool enp1s0f0
Settings for enp1s0f0:
	Supported ports: [ FIBRE ]
	Supported link modes:   1000baseT/Full 
	                        2500baseX/Full 
	Supported pause frame use: Symmetric Receive-only

My last step was to compile a new 2.5G bnx2x driver (bnx2x_warpcore+8727_2_5g_sgmii.patch)
Do you see now 2500baseX/Full in the advertised link modes? The link will not come up unless the fiber is connected and the module is authenticated.

It was just a formality to connect to the SFP module and check the speed of the LAN port.
