freebsd/sys/dev/usb/net/usb_ethernet.h
Pyun YongHyeon 5c6b53d82c This change makes it possible to define driver specific attach
handler such that driver can announce interface capabilities and
can do its own MII attach.  Currently all USB ethernet controllers
have no way to establish a link with pause capabilities. Lack of
checksum offloading support also was one of reason to bring this
change in.

This change adds a couple of wrappers to USB ethernet drivers
(uether_ifmedia_upd, uether_init and uether_start). All exported
functions in uether has prefix uether_ so I think it's more
consistent to have wrappers that follow the convention.
This change preserves ABI/KPI so it should be safe to merge this
change to stable/8.

While I'm here add missing __FBSDID and clean up headers.
