Arge1 link status is not updated

[Pham Viet Ha]

Hi Louiz,

Yes, the LAN ports are on arge0 with 4 PHY ports (0-3). The WAN port is on arge1 with PHY4. This is an AG300H board from Buffalo.

At this time I am using phymask 0x0f for arge0. It looks like that we should use phymask 0x00 for this interface as when the etherswitch/arswitch is enabled, it will attach and manage the 4 LAN ports correctly. 

If I need to update the arge1 link status from inside the switch driver, what should I do? 

Also, the ifnet interfaces are also created during the switch init. How can I make these interfaces available for infconfig command? 


Thanks so much.

Looks like your setup is somewhat different or misconfigured because you have 4 PHYs on arge0 (which is not common).

Can you share your board model and you setup ? We maybe able to help you get it right.
