From 45979c1e424f6a14495a4988343df176cb745f84 Mon Sep 17 00:00:00 2001 From: Rasesh Mody Date: Mon, 8 Aug 2011 16:21:36 +0000 Subject: bna: Introduce ENET as New Driver and FW Interface Change details: - This patch contains the messages, opcodes and structure format for the messages and responses exchanged between driver and the FW. In addition this patch contains the state machine implementation for Ethport, Enet, IOCEth. - Ethport object is responsible for receiving link state events, sending port enable/disable commands to FW. - Enet object is responsible for synchronizing initialization/teardown of tx & rx datapath configuration. - IOCEth object is responsible for init/un-init of IO Controller in the adapter which runs the FW. - This patch also contains code for initialization and resource assignment for Ethport, Enet, IOCEth, Tx, Rx objects.
