From 406adee9a9fc38c11671f26180e694976f45237c Mon Sep 17 00:00:00 2001 From: "Yisen.Zhuang\\(Zhuangyuzeng\\)" Date: Sat, 23 Apr 2016 17:05:07 +0800 Subject: [PATCH] net: hns: add attribute port-idx-in-ae in enet node. This patch parse port-idx-in-ae in enet node. In NIC mode of DSAF, all 6 PHYs of service DSAF are taken as ethernet ports to the CPU. The port-idx-in-ae can be 0 to 5. Here is the diagram: +-----+---------------+ | CPU | +-+-+-+---+-+-+-+-+-+-+ | | | | | | | | debug debug service port port port (0) (0) (0-5) In Switch mode of DSAF, all 6 PHYs of service DSAF are taken as physical ports connect to a LAN Switch while the CPU side assume itself have one single NIC connect to this switch. In this case, the port-idx-in-ae will be 0 only. +-----+-----+------+------+ | CPU | +-+-+-+-+-+-+-+-+-+-+-+-+-+ | | service| port(0) debug debug +------------+ port port | switch | (0) (0) +-+-+-+-+-+-++ | | | | | | external port when port-idx-in-ae is not exists, old attribute port-id will be used (only for compatible purpose, not recommended to use port-id in new code).
