A socket created bound to a specific protocol can receive packets before
it's bound to a specific interface/mac.
It's best to rely on the bind().
This replicates the way packet sockets are created in external/android-clat.
See: ring.c ring_create() and clatd.c configure_packet_socket()

Per http://tools.ietf.org/html/rfc768:
If the computed checksum is zero, it is transmitted as all ones (the
equivalent in one's complement arithmetic). An all zero transmitted
checksum value means that the transmitter generated no checksum (for
debugging or for higher level protocols that don't care).
