d80016310b net/bnxt: fix packet type
The hw flags are not read correctly: the defines
RX_PKT_CMPL_FLAGS_ITYPE_* are not bits but values, so the should not be
tested with if (value & X) but with if ((value & MASK) == X).
This was resulting in a wrong packet type.

For instance, an IPv4/ICMP packet was returning a value of 7 for
the layer 4, which is undefined.

This patch rework the way packet types are processed, to ensure
that only valid packet types will be advertised.

0fc49cbb2c net/bnxt: fix Rx checksum flags
Fix the Rx offload flags when the IP or L4 checksum is seen as incorrect
by the hardware. In this case, the proper value is PKT_RX_IP_CKSUM_BAD.

PKT_RX_IP_CKSUM_NONE means that the checksum may be incorrect in the
packet headers, but the integrity of the IP header is verified. This is
mostly useful for virtual drivers.

There is no update in header content and since ethdev.h included by
ethdev_driver.h, nothing changed from driver point of view, only
logically grouping of APIs. From applications point of view they can't
access to driver specific APIs anymore and they shouldn't.

More PMD specific data structures still remain in ethdev.h because of
inline functions in header use them. Those will be handled separately.

cebe3d7b3d ethdev: remove useless parameter in callback process
The pointer to the user parameter of the callback registration is
automatically pass to the callback function.
There is no point to allow changing this user parameter by a caller.
That's why this parameter is always set to NULL by PMDs and set only
in ethdev layer before calling the callback function.

The history is that the user parameter was initially used
by the callback implementation to pass some information
between the application and the driver:
	c1ceaf3ad0 ("ethdev: add an argument to internal callback function")
Then a new parameter has been added to leave the user parameter
to its standard usage of context given at registration:
	d6af1a13d7 ("ethdev: add return values to callback process API")

The NULL parameter in the internal callback processing function
is now removed. It makes clear that the callback parameter is user
managed and opaque from a DPDK point of view.

Existing vlan_offload_set_t vectors are modified to return

can fail now return their failure codes.

Finally, a vlan_offload_set_t vector is added to virtio
to facilitate dynamically turning VLAN strip on or off.

380a7aab1a mbuf: rename deprecated VLAN flags
PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT are deprecated for a while.
As explained in [1], these flags were kept to let the applications and
PMDs move to the new flag. There is also a need to support Rx vlan
offload without vlan strip (at least for the ixgbe driver).

This patch renames the old flags for this feature, knowing that some
PMDs were using PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT to indicate that
the vlan tci has been saved in the mbuf structure.

It is likely that some PMDs do not set the proper flags when doing vlan
offload, and it would be worth making a pass on all of them.

d5b0924ba6 ethdev: add return value to stats get dev op
The stats_get dev op API doesn't include return value, so PMD cannot
return an error in case of failure at stats getting process time.

Since PCI devices can be removed and there is a time between the
physical removal to the RMV interrupt, the user may get invalid stats
without any indication.

This patch changes the stats_get API return value to be int instead of
void.

All the net PMDs stats_get dev ops are adjusted by this patch.

Only set the vlanonly bit if vlan_nonvlan is clear. Also, allow the
VLAN table to be cleared when vlanonly is set.

Clearing the VLAN table when vlanonly is set will stop all traffic
since it requires all frames to have a VLAN tag, and that tag to be

1cd45aeb32 net/bnxt: support Stratus VF device
This patch adds support for Stratus VF devices.
Other than adding the VF device ID, we also are adding
support for short message format.

The new short firmware message of size 16 bytes points to a location
in host memory that contains the firmware message that the driver
wants the adapter to process. This indirection requires the
firmware to DMA the message into its own memory for processing.

When the firmware receives a Short Command Format, it will DMA the
firmware message from host memory into its internal memory and then
processes the message as it would have if it received the message
directly in the firmware communication channel.

With BCM57454, the number of VFs increase to 1K and so the requirement
for firmware communication channel memory on adapter becomes expensive.
The short firmware message saves the amount of memory required to support
1K VFs on adapter.

   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.

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.

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"

cb6696d220 drivers: update registration macro usage
Modify the PMD_REGISTER_DRIVER macro, adding a name argument to it.  The
addition of a name argument creates a token that can be used for subsequent
macros in the creation of unique symbol names to export additional bits of
information for use by the pmdinfogen tool.  For example:

PMD_REGISTER_DRIVER(ena_driver, ena);

registers the ena_driver struct as it always did, and creates a symbol
const char this_pmd_name0[] __attribute__((used)) = "ena";

which pmdinfogen can search for and extract.  The subsequent macro

DRIVER_REGISTER_PCI_TABLE(ena, ena_pci_id_map);

creates a symbol const char ena_pci_tbl_export[] __attribute__((used)) =
"ena_pci_id_map";

Which allows pmdinfogen to find the pci table of this driver

Using this pattern, we can export arbitrary bits of information.

pmdinfo uses this information to extract hardware support from an object
file and create a json string to make hardware support info discoverable
later.

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.

1d0704f4d7 net/bnxt: add device configure operation
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.

Move init() cleanup into uninit() function
Fix .dev_private_size

New HWRM calls:
bnxt_hwrm_func_driver_register:
	This command is used by the function driver to register
	its information with the HWRM.

bnxt_hwrm_func_driver_unregister:
	This command is used by the function driver to unregister
	with the HWRM.

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.
