Do a boot -v and report which MII driver is currently attaching

FreeBSD: sys/dev/mii/rge*
DragonFly: sys/dev/netif/mii_layer/rge*

There is some fairly minor porting work that needs to be done,
which you can look at by looking at the cvs log history for some
of the other MII source modules in DragonFly.

Please find attached my attempt to import support for the RealTek
8169S/8110S from FreeBSD. This supports my DLink 528(T) Card. Could
someone please review/test? The patch is against HEAD. I ran into two

DragonFly is missing a mii_phy_update() function so I wrote an
rge_phy_update() replacement. I'm not sure this is 100% correct.

The card would not auto-negotiate a 1Gbit connection. I increased the
auto-negotiation interval to 17 seconds from five which solved the

I still use 5 sec as interval value in the updated patch. It works
fine with my TP-Link 1000M switch. Pleae let me know if it does not
work for your re(4)

problem. There was PR report with this problem and solution for re(4)
and a Cisco switch but I can no longer find the link.

I can see why the cards are $12. I'm slightly disappointed that two of
these cards back to back only manage ~150Mbit/s but it's an improvement
over my built-in vr0.

I have those pooool vr(4)s too _

I've installed and tested your patch and everything is working as
expected. I have two RealTek 8169S cards connected via a crossover cable
and have not been able to reproduce the auto-negotiation issues I was
experiencing previously with my patch. (At 5 seconds the negotiation
process would restart before it had a chance to complete causing a loop.)

I've found the links to the commits that change the auto-negotiation
timeout to 17 seconds for gigE cards. This is the setting used by other
gigE drivers such as nsgphy.c and is why I tried this value.

nsgphy.c Revision 1.1.2.2
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/mii/nsgphy.c

Minimal patch to get NetGear622 talking to cisco gigE switches.

mii_physubr.c Revision 1.16
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/mii/mii_physubr.c

Increase gigE negotiation timeout to 17 seconds.

10 seconds is not enough to negotiate a gigE link with a cisco switch
which holds carrier off for several seconds between tries.
