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.
