-// Hold packets in fifo until they are complete.  This prevents slowly-built packets
-//  from clogging up the downstream.  This block will hold up to 255 packets.
-//  Will permanently block if a single packet is bigger than the fifo.
-//  Will also drop any packet with an error signalled on the last line.
-//  This is useful after an ethernet interface to drop packets with bad CRCs.
