ccba2af2db net/bnxt: add additional HWRM debug info
Add the cmd_err and opaque_0 and opaque_1 fields to HWRM error
messages.  These allow better debugging of some classes of HWRM
errors.

84f2c526d3 net/bnxt: support lack of huge pages
rte_malloc_virt2phy() does not return a physical address if huge pages
aren't in use.  Further, rte_memzone->phys_addr is not a physical address.

Use rte_mem_virt2phy() and manually lock pages to support lack of
huge pages.

Also check the return value of rte_mem_virt2phy()

Verify the function returns an address. Otherwise return an error and
log a message.

4535cad395 net/bnxt: handle VF/PF initialization appropriately
1) For a VF, query the firmware to determine if a MAC address is
   already configured. If not configure a random default MAC address.

2) Do not initialize the default completion ring in
   bnxt_alloc_hwrm_rings().

3) While registering for async events with the firmware,
   use func_vf_cfg for a VF and use func_cfg for a PF.

4) Query the VNIC plcmode config using the bnxt_hwrm_vnic_plcmodes_qcfg
   before a VNIC is updated. Reconfigure the VNIC with the plcmode
   configuration queried earlier. Not doing this could overwrite
   the plcmodes in some cases.

5) Reorg the bnxt_handle_fwd_req to properly handle the forwarded
   requests. The previous code did not handle it completely.

b7778e8a1c net/bnxt: refactor to properly allocate resources for PF/VF
1) Move the function reset to bnxt_dev_init.
   On the same lines, setup, enable and request interrupt to init path.
   Memory allocation is also being done in the init path.

2) After a function reset, configure the VFs.  Distribute resources
   evenly between all functions (PF and VF) for now. In the future, this
   should be controllable.

3) The bnxt_vf_info and bnxt_pf_info had lot of duplication. Move the
   common items to struct bnxt. And only unique items specific to PF
   remain in the struct bnxt_pf_info.

4) Program the firmware to allow certain commands sent by a VF.
   Disallowing these will prevent clean VF driver cleanup.

5) Since PF/VF need to allocate resources from a pool in the hardware,
   use func_qcaps and func_qcfg to appropriately query the capabilities
   and available resources.

6) If a PF is being initialized and no VFs are allocated, explicitly
   call func_cfg to allocate the resources.

7) Once resources are requested from the firmware, update local copy
   of resource count in struct bnxt only after sending the func_qcfg to
   make sure the allocation request in the firmware went through.

The changes in this patch will be used by the subsequent patches
to allow proper initialization of PF/VF instance.

Some customers find adding MAC addr to VF sometimes can fail,

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.

5d8f0baf69 log: do not drop debug logs at compile time
Today, all logs whose level is lower than INFO are dropped at
compile-time. This prevents from enabling debug logs at runtime using
--log-level=8.

The rationale was to remove debug logs from the data path at
compile-time, avoiding a test at run-time.

This patch changes the behavior of RTE_LOG() to avoid the compile-time
optimization, and introduces the RTE_LOG_DP() macro that has the same
behavior than the previous RTE_LOG(), for the rare cases where debug
logs are in the data path.

So it is now possible to enable debug logs at run-time by just
specifying --log-level=8. Some drivers still have special compile-time
options to enable more debug log. Maintainers may consider to
remove/reduce them.

unique Device ID for each NPAR partition for each device.  In addition,
ASIC's that are capable of supporting dual media have a unique DID
depending whether they are configured in copper or fiber mode.
This patch adds the necessary DIDs.

As a part of NPAR, we don't allow port settings like speed or flow
control to be changed.

1fe1aaf207 net/bnxt: support Broadcom StrataGX
This patch adds support for the Broadcom StrataGX® BCM5871X
series of Communications Processors.

These ARM based processors target a broad range of networking
applications including virtual CPE (vCPE) and NFV appliances,
10G service routers and gateways, control plane processing for
Ethernet switches, and network attached storage (NAS).

Other than adding the PCI Id for supporting the device,
the patch also adds a memory barrier before the Tx doorbell
and Completing ring doorbell is written to. Since ARM has a
weakly ordered memory model this enforces a strict ordering
of the descriptor writes before the doorbell writes happen.

2f3193cf0f pci: inherit common driver in PCI driver
Remove the 'name' member from rte_pci_driver and move to generic
rte_driver.

Most of the PMD drivers were initially using DRIVER_REGISTER_PCI(<name>..)
as well as assigning a name to eth_driver.pci_drv.name member.
In this patch, only the original DRIVER_REGISTER_PCI(<name>..) name has
been populated into the rte_driver.name member - assignments through
eth_driver has been removed.

c830cb2954 drivers: use PCI registration macro
Simplify crypto and ethdev pci drivers init by using newly introduced
init macros and helpers.
Those drivers then don't need to register as "rte_driver"s anymore.

Exceptions:
- virtio and mlx* use RTE_INIT directly as they have custom initialization
  steps.
- VDEV devices are not modified - they continue to use PMD_REGISTER_DRIVER.

Update documentation for replacing an example referring to
PMD_REGISTER_DRIVER.

2f45703c17 drivers: make driver names consistent
As discussed in the past release, driver names are modified
to be more consistent, and the future driver should follow
this new convention.

Driver names consist of:
"driver category"_"driver folder name"_"optional extra name".

For example:
- Crypto null driver       -> "crypto_null"
- Network IXGBE VF driver  -> "net_ixgbe_vf"
