[Sis-SCPS-INTEREST] SCPS-RI Data Rate

[Feighery, Patrick D.]

Sorry

I looked at the rfile and everything there referenced the TAP
interface, I did not read your configuration line carefully.  In that
case, you need to remove all of the TAP references from the rfile and
replace then with the corresponding entries for TUN references.  See
README.GATEWAY.LINUX.TUN
