For performance reasons, this patch uses 2 VIC RQs per RQ presented to
DPDK.
The VIC requires that each descriptor be marked as either a start of
packet (SOP) descriptor or a non-SOP descriptor. A one RQ solution
requires skipping descriptors when receiving small packets and results
in bad performance when receiving many small packets.
The 2 RQ solution makes use of the VIC feature that allows a receive
on primary queue to 'spill over' into another queue if the receive is
too large to fit in the buffer assigned to the descriptor on the
primary queue. This means that there is no skipping of descriptors
when receiving small packets and results in much better performance.

In this patch we are adding the bnxt_tx_queue_setup_op() and
bnxt_tx_queue_release_op() functions. These will be tied to the
tx_queue_setup and tx_queue_release dev_ops in a subsequent patch.
In these functions we allocate/free memory for the TX queues.
This still requires support to create a TX ring in the ASIC which
will be completed in a future commit. Each Tx queue created via the
tx_queue_setup dev_op will have an associated Tx ring in the hardware.
A Tx request coming on the Tx queue gets sent to the corresponding
Tx ring in the ASIC for subsequent transmission.

Add the L2 filter structure and the alloc/init/free functions for
dealing with them.
A filter is used to identify traffic that contains a matching set of
parameters like unicast or broadcast MAC address or a VLAN tag amongst
other things which then allows the ASIC to direct the incoming traffic
to an appropriate VNIC or Rx ring.
New HWRM calls:
bnxt_hwrm_clear_filter:
Free a L2 filter.
bnxt_hwrm_set_filter
Allocate an An L2 filter or a L2 context.

Structures, macros, and functions for working with completion rings
in the driver.
Completion Ring is used by the Ethernet controller to provide the
status of transmitted & received packets, report errors, report
status changes to the host software, and inter-function forwarding
requests. In addition to the generic ring features, a completion ring
can have a statistics context that has statistics periodically DMAed
to host memory, along with a consumer index.
bnxt_handle_async_event() handles completions not related to a specific
transmit or receive ring such as link status changes which arrive on
the default completion ring.
Other physical or virtual functions on the same device may send an HWRM
command forward request. In this case, we will pass it through
unvalidated. In the future, we will be able to have the PF monitor and
control VF access to the HWRM interface if needed.
New HWRM Calls:
bnxt_hwrm_exec_fwd_resp:
Execute an encapsulated command and forward the response.

Declare generic ring structures and a free() function. These are
generic ring management functions which will be used to create Tx,
Rx and Completion rings in the subsequent patches, and tie them to
the HWRM managed ring resources.
This generic ring structure is shared all the ring types and tracks
the the host Buffer Descriptors (BDs) and the HWRM assigned ID.

Add functions to allocate, initialize, and free vnics.
A VNIC represents a virtual interface. It is a resource in the RX path
of the chip and is used to setup various target actions such as RSS,
MAC filtering etc. for the physical function in use.

The dev_configure_op function calls bnxt_set_hwrm_link_config() to
setup the PHY. This calls the new bnxt_parse_eth_link_*() functions
to translate from the DPDK macro values to those used by HWRM calls,
then calls bnxt_hwrm_port_phy_cfg() to issue the HWRM call.
New HWRM calls:
bnxt_hwrm_port_phy_cfg:
This command configures the PHY device for the port.

Start adding support to use the HWRM API.
Hardware Resource Manager or HWRM in short, is a set of API provided
by the firmware running in the ASIC to manage the various resources.
Initial commit just performs necessary HWRM queries for init, then
fails as before.
Now that struct bnxt is non-zero size, we can set dev_private_size
correctly.
The used HWRM calls so far:
bnxt_hwrm_func_qcaps:
This command returns capabilities of a function.
bnxt_hwrm_ver_get:
This function is called by a driver to determine the HWRM
interface version supported by the HWRM firmware, the
version of HWRM firmware implementation, the name of HWRM
firmware, the versions of other embedded firmwares, and
the names of other embedded firmwares, etc. Gets the
firmware version and interface specifications. Returns
an error if the firmware on the device is not supported
by the driver and ensures the response space is large
enough for the largest possible response.
bnxt_hwrm_queue_qportcfg:
This function is called by a driver to query queue
configuration of a port.
