Control structure for communication between LLC and higher layers

Usage diagram:

The following diagram shows usage relationships between types. Unresolved types are missing from the diagram.

Inheritance diagram:

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Fields:

Name	Type	Description
src	MACAddress	src MAC address (can be left empty when sending)
dest	MACAddress	dest MAC address
etherType	int	used with EthernetIIFrame
interfaceId	int	incoming or outgoing interface (not needed everywhere)
switchPort	int	swich port index (only in swiches)
userPriority	int	802.1d User Priority (UP), 0..7. Note: In 802.11, UP corresponds to 0..7 TID values, and there's a standard static mapping from TID to AC (Access Category)
ssap	int	used with IEEE 802 LLC (see EtherFrameWithLLC)
dsap	int	used with IEEE 802 LLC (see EtherFrameWithLLC)
pauseUnits	int	used with IEEE802CTRL_SENDPAUSE
