Can you ensure that your commit messages are consistently wrapped? Some lines are wrapped others aren't. > Problem is that Packet Processor witch actually can drop packets due to lack > of resources Does the packet processor engage in magic or witchcraft? I suppose some would argue that firmware does "magic"! However, I think you mean "which". :) > 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.

What is the minimum firmware version that supports this? -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
