Hi Ryan and Ian,
  Do we need this code in chromium? We are passing pacing as connection options.
sent_packet_manager_ uses enable pacing flags.

thanks
raman

Hm. Good question. I think we can probably leave this commented out until we're
happy that pacing works as expected. Ian, what do you think?

Acknowledged.

   if (!is_server_) {
     // Pacing will be enabled if the client negotiates it.
     sent_packet_manager_.MaybeEnablePacing();
   }
