Does user level Click still work?

[Leigh Stoller]

Is userlevel Click still supposed to work?

	FromBPF at 1 :: FromBPF(fxp0);
	Print at 2 :: Print(ok);
	Discard at 3 :: Discard;

	FromBPF at 1 -> Print at 2
	    -> Discard at 3;

This exits immediately. I noticed the following code. Does this mean that a
valid configuration is one in which at least one element is permanently
scheduled? 

void
Router::driver()
{
  unsigned c = 10000;
  ElementLink *fl;
  while (fl = scheduled_next(), fl != this && !_please_stop_driver) {
    fl->unschedule();
    ((Element *)fl)->run_scheduled();
    if (c-- == 0) {
      c = 10000;
      wait();
    }
  }
}

Please let me know what you are intending or what I am missing.

Thanks very much!
