Leave congestion group taildrop enabled for all traffic classes when PFC is enabled. Notification threshold is low enough such that it will be hit first and this also ensures that FQs on traffic classes which are not PFC enabled won't drain the buffer pool.
FQ taildrop threshold is kept disabled as long as any form of flow control is on. Since FQ taildrop works with bytes, not number of frames, we can't guarantee it will not interfere with the congestion notification mechanism for all frame sizes.
