net: Indicate whether a socket is a transparent socket
Modify the printout functions for IPv4-TCP, IPv4-UDP, IPv6-TCP, IPv6-UDP,
such that the state for the socket is printed as state = state | 0x80.
The actual socket state is unmodified. This change is required for the
user space to determine whether a socket is a transparent socket, and
to determine if the socket holder intends to consume packets locally
or to forward them to an external processor.
