Not sure if it is necessary to force the default RSS input set as session id for PPPoE, 
So maybe reword to below:
Typically Session Id would be the RSS input set for a PPPoE packet, but as a hint each driver may have different default behavior

  I mean if we use ETH_RSS_PPPoE, itself represents the input set "session id". Maybe I can reword:
  session id is assumed to be the default RSS input set for ETH_RSS_PPPoE.
  Do you think it's ok ?
