9.0 English

This section describes the operation of the priority flow control logic of the core. Priority-based flow control is defined in the IEEE Standard 802.1Qbb. The Ethernet MAC can be configured to transmit and receive priority-based flow control requests. These modes of operation can be independently enabled or disabled.

See MAC Configuration Registers. Operation of the MAC with both PFC and 802.3 flow control enabled is not supported as these modes of operation are mutually exclusive.
