[dpdk-dev] [PATCH v3] ixgbe: support link speed auto-neg on x550em_x

2016-02-26 Thread Wenzhuo Lu
Normally the auto-negotiation is supported by FW. SW need not care about that. But on x550em_x, FW doesn't support auto-neg. As the ports of x550em_x are 10G, if we connect the port will a peer which is 1G, the link will always be down. We need support auto-neg by SW to avoid this link down issue.
