(it may not be a IPv6 question, but unix API question)
based on the RFC2960 statement, what should we do about getservbyport
2nd argument for SCTP connection, and/or /etc/services entries?
my guess is that (1) we need to put "foo/sctp" explicitly into
/etc/services and (2) 2nd argument must be "sctp". this is based on
observation from tcp/udp case (even if there's the same service - such
as http - on the same port, we put separate entries into /etc/services)
