lksctp-tools-devel missing in RH Enterprise Linux 7.2?

I would like to develop an application using sctp. My application was running on RH Enterprise Linux 4.
But on RHEL 7.2 I can't find the file /usr/include/netinet/sctp.h. This file was provided by the rpm package lksctp-tools-devel on previous RH releases but this package doesn't seem to be available for 7.2.

Where can I find this package? Or do I need to install another one on RH 7.2?
Which package provides the file /usr/include/netinet/sctp.h on RH 7.2?

Thank you.
