not connected to the GOP flow control generation mechanism. To solve this issue Armada has firmware running on CM3 CPU dedectated for Flow Control support. Firmware monitors Packet Processor resources and asserts XON/XOFF by writing to Ports Control 0 Register.What is the minimum firmware version that supports this?Support were added to firmware about two years ago.
