sim: dv-sockser: pass up connected state
A few ports rely on internal dv-sockser state in order to detect whether a connection has been made (look for 'extern sockser_addr'). Rather than continuing that tradition, extend the existing status function to return the socket connection status. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
