322bd6e702 net/bnxt: add port representor infrastructure
Defines data structures and code to init/uninit
VF representors during pci_probe and pci_remove
respectively.
Most of the dev_ops for the VF representor are just
stubs for now and will be will be filled out in next patch.

To create a representor using testpmd:
testpmd -c 0xff -wB:D.F,representor=1 -- -i
testpmd -c 0xff -w05:02.0,representor=[1] -- -i

To create a representor using ovs-dpdk:
1. First add the trusted VF port to a bridge
ovs-vsctl add-port ovsbr0 vf_rep1 -- set Interface vf_rep1 type=dpdk
options:dpdk-devargs=0000:06:02.0
2. Add the representor port to the bridge
ovs-vsctl add-port ovsbr0 vf_rep1 -- set Interface vf_rep1 type=dpdk
options:dpdk-devargs=0000:06:02.0,representor=1

fbaf943887 build: remove individual library versions
Since the library versioning for both stable and experimental ABI's is
now managed globally, the LIBABIVER and version variables no longer
serve any useful purpose, and can be removed.

The replacement in Makefiles was done using the following regex:

	^(#.*\n)?LIBABIVER\s*:=\s*\d+\n(\s*\n)?

(LIBABIVER := numbers, optionally preceded by a comment and optionally
succeeded by an empty line)

The replacement for meson files was done using the following regex:

	^(#.*\n)?version\s*=\s*\d+\n(\s*\n)?

(version = numbers, optionally preceded by a comment and optionally
succeeded by an empty line)

[David]: those variables are manually removed for the files:
- drivers/common/qat/Makefile
- lib/librte_eal/meson.build
[David]: the LIBABIVER is restored for the external ethtool example
library.

feb9f680cd mk: optimize directory dependencies
Before this patch, the management of dependencies between directories
had several issues:

- the generation of .depdirs, done at configuration is slow: it can take
  more than one minute on some slow targets (usually ~10s on a standard
  PC without -j).

- for instance, it is possible to express a dependency like:
  - app/foo depends on lib/librte_foo
  - and lib/librte_foo depends on app/bar
  But this won't work because the directories are traversed with a
  depth-first algorithm, so we have to choose between doing 'app' before
  or after 'lib'.

- the script depdirs-rule.sh is too complex.

- we cannot use "make -d" for debug, because the output of make is used for
  the generation of .depdirs.

This patch moves the DEPDIRS-* variables in the upper Makefile, making
the dependencies much easier to calculate. A DEPDIRS variable is still
used to process library dependencies in LDLIBS.

After this commit, "make config" is almost immediate.

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.

For each Tx queue allocated in the PMD driver, a corresponding ring

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.

bnxt_handle_async_event() handles completions not related to a specific
transmit or receive ring such as link status changes which arrive on

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

8e7405f7e4 net/bnxt: declare generic ring structs
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.

9738793f28 net/bnxt: add VNIC functions and structs
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.

804e746c7b 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.

3522681460 net/bnxt: add driver for Broadcom NetXtreme-C devices
This patch adds the initial skeleton for bnxt driver along with the
nic guide, and ties the driver into the build system.
At this point, the driver simply fails init.
