Draytek 2130 manual 4.1.3 3G Backup, Internet, SIM PIN code

	Discard - It determines whether the MAC drops frames after an
	excessive collision has occurred. If yes, a frame is dropped after
	excessive collision. This is IEEE Standard 802.3 half-duplex
	flow control operation.
	Restart - It determines whether the MAC retransmits frames
	after an excessive collision has occurred. If set, a frame is not
	dropped after excessive collisions, but the backoff sequence is
	restarted. This is a violation of IEEE Standard 802.3, but is
	useful in non-dropping half-duplex flow control operation.
Power Control	The Configured column allows for changing the power savings
	mode parameters per port.
