Arge1 link status is not updated

[Pham Viet Ha]

Hi there,

I am running nanobsd on a MIPS platform, which is an AR7161 CPU with AR8316 switch. Both arge interfaces show up however the link status is not correctly updated. 

arge1 (the WAN interface) always show active, even there is no ethernet cable plugged in. 

In a post, Adrian mentioned this (http://lists.freebsd.org/pipermail/freebsd-embedded/2013-July/001871.html):

Then arge1 is glued to this "WAN" PHY. It's not owned by arswitch (but
it could be!) as then arge1 couldn't link to it to get notifications
about link, speed/duplex changes.

My question is how can we make arge1 update its link status (no carrier/active) when the link is disconnected/connected? 

Should it be in arge driver or in the switch driver? 

At this time I compiled and load the switch in a separated module.

Thank you so much.
