847d97894b common/mlx5: modify advanced Rx object via DevX
Implement TIR modification (see mlx5_devx_cmd_modify_tir()) using DevX
API. TIR is the object containing the hashed table of Rx queue. The
functionality to configure/modify this HW-related object is prerequisite
to implement rete_flow_shared_action_update() for shared RSS action in
mlx5 PMD. HW-related structures for TIR modification add in mlx5_prm.h.

a20b2c01a7 build: standardize component names and defines
As discussed on the dpdk-dev mailing list[1], we can make some easy
improvements in standardizing the naming of the various components in DPDK,
and their associated feature-enabled macros.

Following this patch, each library will have the name in format,
'librte_<name>.so', and the macro indicating that library is enabled in the
build will have the form 'RTE_LIB_<NAME>'.

Similarly, for libraries, the equivalent name formats and macros are:
'librte_<class>_<name>.so' and 'RTE_<CLASS>_<NAME>', where class is the
device type taken from the relevant driver subdirectory name, i.e. 'net',
'crypto' etc.

To avoid too many changes at once for end applications, the old macro names
will still be provided in the build in this release, but will be removed
subsequently.

482a1d34b6 common/mlx5: fix PCI address lookup
mlx5 PMDs use the mlx5_dev_to_pci_addr() routine to convert
Infiniband device name to the Bus-Device-Function location
on the PCI bus. The routine returned success even in case of
not found identification string. On caller side it likely
caused the wrong match with the BDF of previous device
resulting in wrong representor and master recognitions.

af86364409 common/mlx5: fix aligned malloc
Before this commit system call memalign was used for aligned
allocations, however memalign is deprecated.

Based on (1) - POSIX requires that memory aligned allocations can be
freed using free. Some systems provide no way to reclaim memory
allocated with memalign (because one can only pass to free a pointer
gotten from malloc, while, memalign would call malloc and then align the
obtained value).
Another issue is that 64/32 bits architectures use a minimal alignment
size. So any requested alignment below the minimal system size can be
simplified by calling malloc.

The glibc implementation allows memory obtained from posix_memalign to
be reclaimed with free.  This commit replaces system call memalign with
system call posix_memalign. It also calls malloc in case the requested
alignment is below the minimal system size.

161d103b23 net/mlx5: add queue start and stop
The mlx5 PMD did not support queue_start and queue_stop eth_dev API
routines, queue could not be suspended and resumed during device
operation.

There is the use case when this feature is crucial for applications:

- there is the secondary process handling the queue
- secondary process crashed/aborted
- some mbufs were allocated or used by secondary application
- some mbufs were allocated by Rx queues to receive packets
- some mbufs were placed to send queue
- queue goes to undefined state

In this case there was no reliable way to recovery queue handling
by restarted secondary process but reset queue to initial state
freeing all involved resources, including buffers involved in queue
operations, reset the mbuf pools, and then reinitialize queue
to working state:

- reset mbuf pool, allocate all mbuf to initialize pool into
  safe state after the crush and allow safe mbuf free calls
- stop queue, free all potentially involved mbufs
- reset mbuf pool again
- start queue, reallocate mbufs needed

This patch introduces the queue start/stop feature with some
limitations:

- hairpin queues are not supported
- it is application responsibility to synchronize start/stop
  with datapath routines, rx/tx_burst must be suspended during
  the queue_start/queue_stop calls
- it is application responsibility to track queue usage and
  provide coordinated queue_start/queue_stop calls from
  secondary and primary processes.
- Rx queues with vectorized Rx routine and engaged CQE
  compression are not supported by this patch currently

38119ebe01 common/mlx5: add DevX command for flex parsers
In order to use dynamic flex parser to parse protocols that is not
supported natively, two steps are needed.

Firstly, creating the parse graph node. There are three parts of the
flex parser: node, arc and sample. Node is the whole structure of a
flex parser, when creating, the length of the protocol should be
specified. Then the input arc(s) is(are) mandatory, it will tell the
HW when to use this parser to parse the packet. For a single parser
node, up to 8 input arcs could be supported and it gives SW ability
to support this protocol over multiple layers. The output arc is
optional and also up to 8 arcs could be supported. If the protocol
is the last header of the stack, then output arc should be NULL. Or
else it should be specified. The protocol type in the arc is used to
indicate the parser pointing to or from this flex parser node. For
output arc, the next header type field offset and size should be set
in the node structure, then the HW could get the proper type of the
next header and decide which parser to point to.
Note: the parsers have two types now, native parser and flex parser.
The arc between two flex parsers are not supported in this stage.

Secondly, querying the sample IDs. If the protocol header parsed
with flex parser needs to used in flow rule offloading, the DW
samples are needed when creating the parse graph node. The offset
of bytes starting from the header needs to be set. After creating
the node successfully, a general object handle will be returned.
This object could be queried with Devx command to get the sample
IDs.
When creating a flow, sample IDs could be used to sample a DW from
the parsed header - 4 continuous bytes starting from the offset. The
flow entry could specify some mask to use part of this DW for
matching. Up to 8 samples could be supported for a single parse
graph node. The offset should not exceed the header length.

The HW resources have some limitation, low layer driver error should
be checked once there is a failure of creating parse graph node.

layers stack, and the input parameter of the header is considered to

matching in the FTE/STE. Now, the type field and only the PC ID, RTC
ID, and DLY MSR ID of the payload will be supported. The masks should
be 00 ff 00 00 ff ff(00) 00 00 in the network order. Two DWs are
needed to support such matching. The mask fields could be zeros to
support some wildcard rules. But it makes no sense to support the
rule matching only on the payload but without matching type field.

The DW samples should be stored after the flex parser creation for
eCPRI. There is no need to query the sample IDs each time when
creating a flow rule with eCPRI item. It will not introduce
insertion rate degradation significantly.

b458bd4cf7 common/mlx5: fix link with ibverbs glue dlopen option
In case the ibverbs glue is a separate library to dlopen,
the PMD library must allocate a glue structure to be filled by dlopen.

The glue management was in mlx5_common.c and moved to mlx5_common_os.c,
but the variable allocation was not removed from the original file.
The consequence was a link failure, if ibverbs dlopen option is enabled,
because of the redefinition of the variable (with GCC 10):
	multiple definition of 'mlx5_glue'

The original definition is removed to keep only the one moved
in the Linux sub-directory.

3590881b37 common/mlx5: fix physical port name pattern recognition
This patch makes the Infiniband device physical port name
recognition more strict. Currently mlx5 PMD might recognize
the names like "pf0sf0" erroneously as "pf0" and the wrong
device type (host PF representor) is reported.

The names like "pf0sf0" belong to PCI subfunctions which
is currently not supported by mlx5 PMD and this false
recognition must be eliminated.

43e73483a4 devtools: forbid variable declaration inside for
Some compilers raise an error when declaring a variable
in the middle of a function. This is a C99 allowance.
Even if DPDK switches globally to C99 or C11 standard,
the coding rules are for declarations at the beginning
of a block:
http://doc.dpdk.org/guides/contributing/coding_style.html#local-variables

This coding style is enforced by adding a check of
the common patterns like "for (int i;"

The occurrences of the checked pattern are fixed:
	'for *(\(char\|u\?int\|unsigned\|s\?size_t\)'
In the file dpaa2_sparser.c, the fix is to remove the unused macros.
