ea6101a8e4 ethdev: fix port close in secondary process
Secondary process needs to close device to release process private
resources.  But secondary process should not be obliged to wait for
device stop before closing ethdev.

78b82063df common/sfc_efx/base: manage VNIC MAC address by MCDI handle
The board admin may need to assign a MAC address to a guest
VNIC identified by its MCDI handle. Provide an API for that.

In the case when a libefx-based driver is used at the guest,
it will need to check its MAC address using the symmetrical
API if the admin has tweaked it by means of its representor.

b85f50487e common/sfc_efx/base: convert EFX PCIe INTF to MCDI value
When the driver queries its PCIe interface type via MCDI,
the value from the response is translated to an EFX enum.

592ab76f9f app/testpmd: register driver specific commands
Introduce a testpmd API so that drivers can register specific commands.

A driver can list some files to compile with testpmd, by setting them
in the testpmd_sources (driver local) meson variable.
drivers/meson.build then takes care of appending this to a global meson
variable, and adding the driver to testpmd dependency.

Note: testpmd.h is fixed to that it is self sufficient when being
included.

unnecessary page selection where quick access is required.

When rte_eth_link_get_nowait() is called frequently with LSC disabled by
self-developed applications, eventually the PHY status register will be
accessed frequently. It will cause internal PHY init failure, if they
are done simultaneously. So there is a protection added for internal PHY

b77d3318d6 ethdev: prohibit polling stopped queue
Whether it is allowed to call Rx/Tx functions for a stopped queue
was undocumented. Some PMDs make this behavior a no-op
either by explicitly checking the queue state
or by the way how their routines are implemented or HW works.

No-op behavior may be convenient for application developers.
But it also means that pollers of stopped queues
would go all the way down to PMD Rx/Tx routines, wasting cycles.
Some PMDs would do a check for the queue state on data path,
even though it may never be needed for a particular application.
Also, use cases for stopping queues or starting them deferred
do not logically require polling stopped queues.

Use case 1: a secondary that was polling the queue has crashed,
the primary is doing a recovery to free all mbufs.
By definition the queue to be restarted is not polled.

Use case 2: deferred queue start or queue reconfiguration.
The polling thread must be synchronized anyway,
because queue start and stop are non-atomic.

Prohibit calling Rx/Tx functions on stopped queues.

e17cb41db7 net/ipn3ke: fix xstats get return if xstats is null
Many user (e.g. telemetry) invokes rte_eth_xstats_get(port_id, NULL, 0)
to retrieve the required number of elements, but currently ipn3ke PMD
returns zero when xstats is null.

Dedicated check for xstats vs null is not required, since ethdev layer
guarantees that it may be null only if number of entries n is 0 (which
is definitely smaller than total xstats count).

485df8847a ethdev: clarify null location case in xstats get
When xstats location is null in rte_eth_xstats_get() the return value
is not clearly specified.  Some PMDs (eg. hns3/ipn3ke/mvpp2/axgbe) return
zero while others return the required number of elements.

In this patch, special parameter combinations are restricted:
 1. highlight that xstats location may be null if and only if n is 0.
 2. amend n parameter description to specify that if n is lower than
    the required number of elements, the function returns the required
    number of elements.
 3. specify that if n is zero, the xstats must be NULL, the function
    returns the required number of elements (a duplicate which should
    help to not very attentive readers).

Add sanity check for null xstats and non-zero n case on API level to
make it unnecessary to care about it in drivers.

1945c64674 app/testpmd: perform SW IP checksum for GRO/GSO packets
The GRO/GSO library doesn't re-calculate checksums for
merged/fragmented packets. If users want the packets to
have correct IP checksums, they should select HW IP
checksum calculation for the port which the packets are
transmitted to. But if the port doesn't support HW IP
checksum, users may perform a SW IP checksum.
