I have merged the missing inclusion of if_rereg.h in into following
updated patch:

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)

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.
