commit 7bc21f45041b9e2619e59c9c1f8a2368f0bb0aa1

Update description of net.sctp.sctp_rmem and net.sctp.sctp_wmem tunables
sctp does not use second and third ("default" and "max") values
of sctp_(r|w)mem tunables. The format is the same and tcp_(r|w)mem
but the meaning is different so make the documentation explicit to
avoid confusion.
