File dsniff-2.4-link_layer_offset.patch of Package dsniff

Patch by Robert Scheck <robert@fedoraproject.org> for dsniff >= 2.4b1, that
adds further link layer offsets; inspirated from the original DLT_LINUX_SLL
patch by Roland Kletzing <devzero@web.de>. This patch supersedes the Debian
patch by Joerg Dorchain <joerg@dorchain.net> which adds tcpkill support for
handling PPP interfaces. So for some further information, please also have
a look to Debian bug ID #572516.
