forked from KolibriOS/kolibrios
Bugfixes in net branch:
-Disabled UDP remote IP checking because it blocks valid packets in certain situations (DNS resolving) -Removed device '0' (application level) as default device because it was not correctly implemented and would require a lot of changes. Yet need to find a better solution for this. git-svn-id: svn://kolibrios.org@2366 a494cfbc-eb01-0410-851d-a64ba20cac60
