* Instead, added a new function is_local_link_address() which returns the interface with the matching link level address, and can additionally test for unconfigured interfaces. * Merged the two versions of fill_sockaddr_in() together in ipv4.cpp. * ipv4 now uses the new is_local_link_address() function to figure out whether the received packet should be processed or not. This should fix a few DHCP issues with multiple and configured interfaces as recently explained on the mailing list. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34466 a95241bf-73f2-0310-859d-f6bbb57e9c96
