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. 
All releases from 18.09 should has it.

Please add that vital bit of information somewhere appropriate.
I would not be surprised if people are still running e.g. 17.10
on some of their Armada 8040 boards. My Macchiatobin which is
acting as a server currently has 17.10, although I plan to upgrade
it to 18.12 in about three to six months time, once I've well and
truely proven that my ext4 problems are resolved.
