sctp: allow setting path_maxrxt independent of SPP_PMTUD_ENABLE
Andrei Pelinescu-Onciul [Mon, 23 Nov 2009 20:53:57 +0000 (15:53 -0500)]
Since draft-ietf-tsvwg-sctpsocket-15.txt, setting the
SPP_MTUD_ENABLE flag when changing pathmaxrxt via the
SCTP_PEER_ADDR_PARAMS setsockopt is not required any
longer.
