2.7. MAC Flow Control Interface

The MAC flow control interface is available for each supported port within a reconfiguration group.
The table displays the interface signals for different numbers of ports. All interface signals are clocked by the i_clk_tx clock. For 10GE/25GE channels, all interface signals are asynchronous.
Table 33.  Signals of the MAC Flow Control Interface SignalsFor signals description, refer to the F-Tile Ethernet Intel FPGA Hard IP User Guide.
