* Made the pointers const. * Changed how the ARP module maintains its arp_entry::request_buffer: it now uses the atomic_pointer*() functions to make sure there is no race condition, and it's deleted only once. * Getting an ARP entry would return uninitialized data, if the entry hadn't been resolved yet. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25263 a95241bf-73f2-0310-859d-f6bbb57e9c96
