Attansic L2 Fast Ethernet driver for Haiku. Port of FreeBSD driver from:
http://www.SpringDaemons.com/stas/if_ae-1214569185.tar.bz2 (This is the wired NIC on the Asus EEE PC!) NOTE: It is not in the image because it currently still crashes, will look into that soon. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27290 a95241bf-73f2-0310-859d-f6bbb57e9c96
