net/bnxt: add initial Rx code

This patch adds initial implementation of rx_pkt_burst() function for Rx.
bnxt_recv_pkts() is the top level function for doing Rx.

This patch also adds code to allocate rings in the ASIC.

For each Rx queue allocated in the PMD driver, a corresponding ring
in hardware will be created. Every time a frame is received a Rx ring
is selected based on the hardware configuration like RSS, MAC or VLAN,
COS and such. The hardware uses a completion ring to indicate the
availability of a packet.

This patch also brings in functions like bnxt_init_one_rx_ring()
bnxt_init_rx_ring_struct() which initializes various structures before
a Rx can begin.

bnxt_init_rxbds() initializes the Rx Buffer Descriptors while
bnxt_alloc_rx_data() allocates a buffer in the host to receive the
incoming packet.

net/bnxt: add initial Tx code

Initial implementation of tx_pkt_burst for transmit.
bnxt_xmit_pkts() is the top level function that is called during Tx.

bnxt_handle_tx_cp() is used to check and process the Tx completions
generated for the Tx Buffer Descriptors sent by the hardware.

This patch also adds code to allocate rings in the hardware.
For each Tx queue allocated in the PMD driver, a corresponding ring
in hardware will be created. Every time a Tx request is initiated
via the bnxt_xmit_pkts() call, a Buffer Descriptor is created and
is sent to the hardware via the associated Tx ring.

On completing the Tx operation, the hardware will generates the status
in the form of a completion. This completion is processed by the
bnxt_handle_tx_cp() function.

Functions like bnxt_init_tx_ring_struct() and bnxt_init_one_tx_ring()
are used to initialize various members of the structure before
starting Tx operations.

In this patch we are adding the bnxt_rx_queue_setup_op() and
bnxt_rx_queue_release_op() functions. These will be tied to the
rx_queue_setup and rx_queue_release dev_ops in a subsequent patch.
In these functions we allocate/free memory for the RX queues.

This still requires support to create a RX ring in the ASIC which
will be completed in a future commit. Each Rx queue created via the
rx_queue_setup dev_op will have an associated Rx ring in the hardware.

The Rx logic in the hardware picks a Rx ring for each Rx frame received
by the hardware depending on the properties like RSS, MAC and VLAN
settings configured in the hardware. These packets in the end arrive
on the Rx queue corresponding to the Rx ring in the hardware.

We are also adding some functions like bnxt_mq_rx_configure()
bnxt_free_rx_mbufs() and bnxt_free_rxq_stats() which will be used in
subsequent patches.

We are also adding hwrm_vnic_rss_cfg_* structures, which will be used
in subsequent patches to enable RSS configuration.

net/bnxt: add hardware resource manager init code

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.
