Add a new interface for commands execution that allows the caller to wait for the command's completion in a busy-wait loop (polling mode). This is useful if we want to execute a command in a polling mode while the driver is working in events mode for the rest of the commands. This interface will be used in the downstream patches.

Currently when firmware command gets stuck or it takes long time to complete, the driver command will get timeout and the command slot is freed and can be used for new commands, and if the firmware receive new command on the old busy slot its behavior is unexpected and this could be harmful. To fix this when the driver command gets timeout we return failure, but we don't free the command slot and we wait for the firmware to explicitly respond to that command. Once all the entries are busy we will stop processing new firmware commands.

In old FWs query ISSI command is not supported and for some of those FWs it might fail with status other than "MLX5_CMD_STAT_BAD_OP_ERR". In such case instead of failing the driver load, we will treat any FW status other than 0 for Query ISSI FW command as ISSI not supported and assume ISSI=0 (most basic driver/FW interface). In case of driver syndrom (query ISSI failure by driver) we will fail driver load.

TSAR (stands for Transmit Scheduling ARbiter) is a hardware component that is responsible for selecting the next entity to serve on the transmit path. The arbitration defines the QoS policy between the agents connected to the TSAR. The TSAR is a consist two main features: 1) BW Allocation between agents: The TSAR implements a defecit weighted round robin between the agents. Each agent attached to the TSAR is assigned with a weight and it is awarded transmission tokens according to this weight. 2) Rate limer per agent: Each agent attached to the TSAR is (optionally) assigned with a rate limit. TSAR will not allow scheduling for an agent exceeding its defined rate limit. In this patch we implement the API of manipulating the TSAR.

The current implementation does not handle timeout in case of command with callback request, and this can lead to deadlock if the command doesn't get fw response. Add delayed callback timeout work before posting the command to fw. In case of real fw command completion we will cancel the delayed work.

This patch implement the pci_error_handlers for mlx5_core which allow the driver to recover from PCI error. Once an error is detected in the PCI, the mlx5_pci_err_detected is called and it: 1) Marks the device to be in 'Internal Error' state. 2) Dispatches an event to the mlx5_ib to flush all the outstanding cqes with error. 3) Returns all the on going commands with error. 4) Unloads the driver. Afterwards, the FW is reset and mlx5_pci_slot_reset is called and it enables the device and restore it's pci state. If the later succeeds, mlx5_pci_resume is called, and it loads the SW stack.

In preparation to handling system errors at the mlx5_core level, change the interface of cmd_work_handler to accept a 64 bit argument for the vector. This allows to encode a flag that signifies when the handler is called as a result of a driver logic that wishes to terminate commands that the hardware may not be able to terminate. Such command completions are detected at the handler and proper return status is encoded. To be able to terminate page handler commands, we make sure to set the corresponding bit in the bitmask.

In the new flow, we separate the pci initialization and teardown from the initialization and teardown of the other resources. init_one calls mlx5_pci_init that handles the pci resources initialization. It then calls mlx5_load_one to initialize the remainder of the resources. When removing a device, remove_one is invoked. However, now remove_one calls mlx5_unload_one to free all the resources except the pci resources. When mlx5_unload_one returns, mlx5_pci_close is called to free the pci resources. The above separation will allow us to implement the pci error handlers and suspend and resume callbacks.

This is the Ethernet part of the driver for the Mellanox ConnectX(R)-4 Single/Dual-Port Adapter supporting 100Gb/s with VPI. The driver extends the existing mlx5 driver with Ethernet functionality. This patch contains the driver entry points but does not include transmit and receive (see the previous patch in the series) routines. It also adds the option MLX5_CORE_EN to Kconfig to enable/disable the Ethernet functionality. Currently, Kconfig is programmed to make Ethernet and Infiniband functionality mutally exclusive. Also changed MLX5_INFINIBAND to be depandant on MLX5_CORE instead of selecting it, since MLX5_CORE could be selected without MLX5_INFINIBAND being selected.
