haiku/headers/posix/net/if.h
Axel Dörfler 1a3ab92b81 * Rewrote ether_driver.h, removed some BONE stuff we don't support at this point;
it might also be a good idea to change the constants to better match the usual
  style.
* Added a BSD-style if_media.h.
* Added interface flags IFF_LINK, IFF_AUTO_CONFIGURED, and IFF_CONFIGURING. The
  former will be set automatically by the stack, the rest will be set by the
  net_server depending on the current state.
