Title: PCS FIFO Empty condition

Hi,

What action should be taken by the transmit PCS FIFO, when it goes EMPTY (may be in between a packet-data, or IPG) due to some conditions?

My understanding is that it should continuously insert idles till normal condition is restored. But is it also necessary to specifically insert atleast one ERROR column under this condition? The receive MAC on the other side is going to discard the respective packet under both the conditions (since packet gets broken). So, does the PHY need to indicate empty through the error indication?

regards,
Anupama
