Comparing Mutiqueue Support Linux vs FreeBSD

[Takuya ASADA]

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.
