destination port, packets from the non-flow control port
may be dropped. This is to prevent the flow control port
from being flow controlled for an extended period of time.
0, in this mode, if a flow control port and a non-flow
control port talk to the same destination port, the flow
control port will be flow controlled. This may not be “fair”
