* Since JMicron generously send me one of their ethernet cards to add support
to Haiku for them, I finally got around taking a look at their FreeBSD drivers, and imported them into our repository. * They don't compile yet -- looks like our FreeBSD compatibility layer needs some further improvements. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29445 a95241bf-73f2-0310-859d-f6bbb57e9c96
