When a half-duplex device was not able to handle the amount
of data it was receiving from an end station, it collided with it
(faked a collision by sourcing JAM). Thus all devices on the
shared LAN would have to back-off, and then try to retransmit.
The device could keep on colliding, so the other end station
won’t loss its packets.
Default: Enabled per port
