SetPacketType sets passing packets' packet type annotations to TYPE. The
packet type annotation tells Linux about the packet's link-level
characteristics. For example, was the packet sent directly to this host, or
was it broadcast? TYPE should be one of `C<HOST>', `C<BROADCAST>',
`C<MULTICAST>', `C<OTHERHOST>', `C<OUTGOING>', or `C<LOOPBACK>'. */
