doc: update flow API guide for rule removal on stop

There is a discrepancy between ethdev API and flow rules guide
regarding flow rules maintenance after port stop.
librte_ethdev.h declares that flow rules will not be stored in PMD
after port stop:
>>>>> Quote start
 Please note that some configuration is not stored between calls to
 rte_eth_dev_stop()/rte_eth_dev_start(). The following configuration
 will be retained:

 - MTU
 - flow control settings
 - receive mode configuration (promiscuous mode, all-multicast mode,
   hardware checksum mode, RSS/VMDQ settings etc.)
 - VLAN filtering configuration
 - default MAC address
 - MAC addresses supplied to MAC address array
 - flow director filtering mode (but not filtering rules)
 - NIC queue statistics mappings
<<<< Quote end

PMD cannot always correctly restore flow rules after port stop / port
start because application may alter port configuration after port stop
without PMD knowledge about undergoing changes.  Consider the
following scenario:
application configures 2 queues 0 and 1 and creates a flow rule with
'queue index 1' action. After that application stops the port and
removes queue 1.
Although PMD can implement flow rule shadow copy to be used for
restore after port start, attempt to restore flow rule from shadow
will fail in example above and PMD could not notify application about
that failure.  As the result, flow rules map in HW will differ from
what application expects.  In addition, flow rules shadow copy used
for port start restore consumes considerable amount of system memory,
especially in systems with millions of flow rules.

regex/mlx5: fix crash on probe failure

The mlx5_regex_pci_probe function allocates a mlx5_regex_priv structure
using rte_zmalloc.

If the allocation fails, the function jumps to the dev_error label in
order to release previously allocated resources in the function.
However, in the dev_error label it attempts to refer to the internal
fields of the priv structure and if its allocation fails (as in this
case) it is actually dereferencing to NULL.

Replace the jump with an error label.

For kupeng 930, there are 3 registers to control the enable
status of a TQP(i.e. task queue pair, include a txq and a rxq).
One of them controls whether the TQP is enabled, and the other
two controls whether the rxq and txq are enabled. The registers

Currently, when the number of rxq is not equal to the number of txq, the
unused rxqs or txqs are not disabled by driver, so these unused queues

net/mlx5: add wire vport hint

The kernel can use two approaches to distinguish the E-Switch
source vport in the packet metadata - either with dedicated
source_port field or register C0. To eliminate the extra source
vport matching in the hardware the source_port field can be
set to specific values (0xFFFF) for the wire source port.

This match can be applied to recognize wire port only in FDB
domain. Missing the register C0 match in the NIC Rx domain causes
incorrect representor steering within shared IB device ports
and must be always specified (if kernel uses this approach).

common/octeontx2: fix mbox response by syncing data types

Syncing the data types of msix offset mbox response structure
fields wrt rvu_pfvf structure as in msix offset mbox handler,
respective block LFs response field is initialised with rvu_pfvf
and mismatch in the data types of respective fields may lead
to issues.

This mismatch in data types resulted in a bug where no sso msix
offsets are returned. For 256 SSO hwgrps, 256 msix offsets
are required, but since num of sso lf field (rsp->sso) in
response structure is u8 and is initialised with same field
in pfvf structure viz u16, value 256 corresponds to 0 hence
no sso_msixoff.
Similar mbox changes are required in kernel side also which are
available in marvell SDK version SDK-11.0.

The commit d2d57605522d ("net/mlx5: fix Rx queue count calculation") is
incorrect because the count calculation is wrong for the next cqe:

Example:

C | a | e0 | e1 | e2 | e3 | e4 | e5 | C | a | e0

There are 2 compressed set of packets in the first queue. For the first
set, n is computed correctly.

But for the second, n is not computed properly. Because the zip context
is for the first set. The  second set is not yet decompressed, so
there are no context.

To fix the issue, we should only use the zip context for the first CQEs
series.

net/mlx5: fix RSS queue type validation

When the RSS queues' types are not uniformed, i.e, mixed with normal Rx
queue and hairpin queue, PMD accept this flow after commit[1] instead of
rejecting it.

This because commit[1] creates Rx queue object as DevX type via DevX API
instead of IBV type via Verbs, in which the latter will check the queues'
type when creating Verbs ind table but the former doesn't check when
creating DevX ind table.

However, in any case, logically PMD should check whether the input
configuration of RSS action is reasonable or not, which should
include queues' type check as well as the others.

So add the check of RSS queues' type in validation function to fix issue.
