Jeff Kirsher 88f07484cc drivers/net/ethernet/*: Enabled vendor Kconfig options
Based on finds for Stephen Rothwell, where current defconfig's
enable a ethernet driver and it is not compiled due to the newly
added NET_VENDOR_* component of Kconfig.

This patch enables all the "new" Kconfig options so that current
defconfig's will continue to compile the expected drivers.  In
addition, by enabling all the new Kconfig options does not add
any un-expected options.

Rasesh Mody 078086f3c1 bna: ENET and Tx Rx Redesign Enablement
Change details:
This patch contains additional structure and function definition changes
that are required to enable the new msgq/enet/txrx redesign introduced
by the previous 4 patches.
 - structure and function definition changes to header files as a result
   of Ethport, Enet, IOCEth, Tx, Rx redesign.
 - ethtool changes to use new enet function and definitions
 - Set number of Tx and Rx queues bassed on underlying hardware. Define
   separate macros for maximum and supported numbers of Tx and Rx queues
   based on underlying hardware. Take VLAN header into account for MTU
   calculation. Default to INTx mode when pci_enable_msix() fails. Set a
   bit in Rx poll routine, check and wait for that bit to be cleared in
   the cleanup routine before proceeding.
 - The TX and Rx coalesce settings are programmed in steps of 5 us. The value
   that are not divisible by 5 are rounded to the next lower number. This was
   causing the value os 1 to 4 to be rounded to 0, which is an invalid setting.
   When creating Rx and Tx object, we are currently assigning the default
   values of Rx and Tx coalescing_timeo. If these values are changed in the
   driver to a different value, the change is lost during such operations as
   MTU change. In order to avoid that, pass the configured value of
   coalescing_timeo before Rx and Tx object creation. Fix
   bnad_tx_coalescing_timeo_set() so it applies to all the Tx objects.
 - Reorg uninitialization path in case of pci_probe failure.
 - Hardware clock setup changes to pass asic generation, port modes and
   asic mode as part firmware boot parameters to firmware.
 - FW mailbox interface changes to defined asic specific mailbox interfaces.
   h/w mailbox interfaces take 8-bit FIDs and 2-bit port id for owner. Cleaned
   up mailbox definitions and usage for new and old HW. Eliminated usage of
   ASIC ID. MSI-X vector assignment and programming done by firmware. Fixed
   host offsets for CPE/RME queue registers.
 - Implement polling mechanism for FW ready to have poll mechanism replaces
   the current interrupt based FW READY method. The timer based poll routine
   in IOC will query the ioc_fwstate register to see if there is a state
   change in FW, and sends the READY event. Removed infrastructure needed to
   support mbox READY event from fw as well as IOC code.
 - Move FW init to HW init. Handle the case where PCI mapping goes away when
   IOCPF state machine is waiting for semaphore.
 - Add IOC mbox call back to client indicating that the command is sent.

Rasesh Mody f3bd517323 bna: Tx and Rx Redesign
Change details:
 - This patch contains the changes as a result of redesigning of Tx, Rx data
   path setup. In the old design, setting up Txqs, Rxqs were done in the driver.
   With the new design, most of the hardware setup steps for the Txq, Rxqs are
   moved to FW. Host driver issues commands to FW through the message queue to
   setup/teardown tx, rx data path. FW performs necessary steps and responds
   back to the driver with a status.
 - As a result of this redesign, the state machine implementation for Tx, Rx
   objects have changed significantly. Instead of doing the raw register access,
   these state machines mostly send a command to FW and wait for response and
   take the next action. In addition to tx, rx datapath setup, this patch also
   deals with rx filter configuration - such as unicast address, multicast
   address, vlan filter, promiscuous mode etc.

Rasesh Mody 45979c1e42 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.

Rasesh Mody af027a34f3 bna: MSGQ Implementation
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.
