haiku/headers/posix/net/if.h
Axel Dörfler 9d771afb39 * Added Haiku specific socket ioctls to configure the interface aliases:
SIOC_IF_ALIAS_ADD, SIOC_IF_ALIAS_REMOVE, SIOC_IF_ALIAS_GET, SIOC_ALIAS_SET,
  and SIOC_IF_ALIAS_COUNT.
* Implemented all of those new ioctls, though they are yet untested.
* Added ifreq::ifr_data, and removed the hack in the FreeBSD compat if.h
  header.
* Minor cleanup.
