Masatake,

Red Hat is the author of the totemnet file and can provide that code
under GPL if you like.  We cannot modify the license for libtomcrypt as
we are not the authors.  Feel free to change the license for that
particular code you rewrote in the link

> Could you see
https://github.com/masatake/wireshark-plugin-rhcs/blob/master/src/packet-corosync-totemnet.c#L156

under a GPL license if it helps move things along.
