Hi Ben, this was a known issue on an older package version, and since 
you asked, we realized that the version on intel.com hasn't been updated 
in a long time, and so doesn't have the fix.

We are working to correct the internal issues that lead to this stale 
package being left there and not updated, and are grateful you pointed 
us to the issue!

Please keep an eye out for the intel.com download page to be updated 
with the latest PPPoE package. Once you have that, RSS should start 
working correctly after loading the newer package.

Thanks for your patience, I don't have a direct ETA on this, but I did 
start the ball rolling internally.
