2.1.1.21. F-Tile Ethernet Hard IP for 10G-200G RX Priority Flow Control (PFC) longer duration of o_rx_pfc port asserted than configured quanta time issue

Description

When using the F-Tile Ethernet Hard IP for 10G-200G with PFC enabled, the o_rx_pfc port is asserted for a longer duration than configured quanta time, when all the following conditions are met:
  • During the processing state of PAUSE state, if new oversized frame is received
  • Frame size larger than maximum frame size set by user during the design generation in the F-Tile Ethernet Hard IP GUI
  • Enforce maximum frame size option in F-Tile Ethernet Hard IP GUI is enabled setting the truncation bit

Workaround

When the Forward RX pause requests option in the F-Tile Ethernet Hard IP is enabled, you must disable the enforce maximum frame size option in the IP GUI.

When the enforce maximum frame size option is required, set the TX maximum frame size and RX maximum frame size to be greater than the incoming frame size.
