[DCCP]: Check if already in the CLOSING state in dccp_rcv_closereq
Arnaldo Carvalho de Melo [Tue, 13 Sep 2005 22:03:15 +0000 (19:03 -0300)]
It is possible to receive more than one CLOSEREQ packet if the
CLOSE packet sent in response is somehow lost, change the state
to DCCP_CLOSING only on the first CLOSEREQ packet received.
