Suggestion would be to check the IEEE 802.3ad specifications regarding auto-negotiation. In short (paraphrased), auto-negotiation determines the link characteristics with its link partner during initialization. During auto-negotiation, each link partner advertizes which link speeds (10, 100 or 1000 Mbps) and duplex modes (full or half) it can support, and also whether it supports flow control. If autonegotiation is disabled, the link will not initiate or respond to autonegotiation, so the link will not know if the link partner supports flow control. That is why flow control is disabled. -- Cheers, Jeff -- Kernelnewbies: Help each other learn about the Linux kernel.
