2011-08-11	bna: Introduce ENET as New Driver and FW Interface	Rasesh Mody
	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.

2011-08-11	bna: MSGQ Implementation	Rasesh Mody
	Change details: - Currently modules communicate with the FW using 32 byte command and response register. This limits the size of the command and response messages exchanged with the FW to 32 bytes. We need a mechanism to exchange the comamnds and responses exchange with FW that exceeds 32 bytes. - MSGQ implementation provides that facility. It removes the assumption that command/response queue size is precisely calculated to accommodate all concurrent FW commands/responses. The queue depth is made variable now, defined by a macro. A waiting command list is implemented to hold all the commands when there is no place in the command queue. Callback is implemented for each command entry to invoke the module posting the command, when there is space in the command queue and the command was finally posted to the queue. Module/Object information is embedded in the response for tracking purpose. Signed-off-by: Rasesh Mody <rmody@brocade.com> Signed-off-by: David S. Miller <davem@davemloft.net>
