net: pass back whether socket was empty post accept
This adds an 'is_empty' argument to struct proto_accept_arg, which can
be used to pass back information on whether or not the given socket has
more connections to accept post the one just accepted.
To utilize this information, the caller should initialize the 'is_empty'
field to, eg, -1 and then check for 0/1 after the accept. If the field
has been set, the caller knows whether there are more pending connections
or not. If the field remains -1 after the accept call, the protocol
doesn't support passing back this information.
This patch wires it up for ipv4/6 TCP.
