Re: disabling mediaopts for if_wm(4)

[Brian Buhrow]

Hello.  You only disable autonegotiation on copper ports if you set speed
or duplex to 10 or 100 mbits/sec.  Setting the speed to 1000-mbits/sec
simply removes 10 or 100 mbits/sec choices from the autonegotiation process
and NetBSD will only offer 1000-mbits/sec as a negotiable choice.  But,
strictly speaking, autonegotiation is still enabled if 1000-mbits/sec is
"nailed" by ifconfig.
See sys/dev/mii/mii_physubr.c for details.
