Maybe we need to add some more generic APIs on NIC driver's ioctl, and invoke it from ifconfig. Or if you hate to add things on ifconfig, just make another command like ethtool from scratch. And driver can export driver specific things via sysctl, some driver already doing in that way. 2013=E5=B9=B46=E6=9C=8827=E6=97=A5=E6=9C=A8=E6=9B=9C=E6=97=A5 Adrian Chadd = adrian@freebsd.org: > ethtool is just a passthrough.
