4e8f2d6a6a compress/qat: add log for IM buffer too small
Display trace if error returned from firmware is likely due
to intermediate buffers being too small for the compressed
output. Update documentation to explain this error case
and to clarify intermediate buffer memory usage.

fe1606e013 crypto/openssl: fix RSA verify operation
In lib cryptodev, RSA verify operation inputs plain message text and
corresponding signature and expected to return
RTE_CRYPTO_OP_STATUS_SUCCESS/FAILURE on a signature match/mismatch.
Current OpenSSL PMD RSA verify implementation overrides application passed
sign input by decrypted output which isn't expected.

This patch addresses this issue in OpenSSL PMD. Now, OpenSSL PMD use
tmp buffer to pass to OpenSSL sign API and memcmp output with
original plain text to verify signature match.
Set op->status = RTE_CRYPTO_OP_STATUS_ERROR on signature mismatch.

6c99085d97 net/vmxnet3: fix hot-unplug
The vmxnet3 driver can't call back into dev_close(), and possibly
dev_stop(), in dev_uninit().  When dev_uninit() is called, anything
that those routines would want to clean up has already been released.
Further, for complete cleanup, it is necessary to release any of the
queue resources during dev_close().
This allows a vmxnet3 device to be hot-unplugged without leaking
queues.
Also set RTE_ETH_DEV_CLOSE_REMOVE on close so that the port resources
can be deallocated.
Return EBUSY if remove is called before stop.

fe822eb8c5 bus/pci: use IOVA DMA mask check when setting IOVA mode
Currently the code precludes IOVA mode if IOMMU hardware reports
less addressing bits than necessary for full virtual memory range.

Although VT-d emulation currently only supports 39 bits, it could
be iovas for allocated memlory being within that supported range.
This patch allows IOVA mode in such a case adding a call to
rte_eal_check_dma_mask using the reported addressing bits by the
IOMMU hardware.

Indeed, memory initialization code has been modified for using lower
virtual addresses than those used by the kernel for 64 bits processes
by default, and therefore memsegs iovas can use 39 bits or less for
most systems. And this is likely 100% true for VMs.

NICs uses different delays up to a second during their

same CPU core. These busy polling are the rudiments that came
from the kernel drivers where you can not sleep in interrupt
context, but as we're in userspace, we're able and should
sleep to allow other threads to run.
Delays never called on rx/tx path, so this should not affect

3a8207423a net/mlx5: close all ports on remove
With the introduction of representors several eth devices are using
the same rte device (e.g. a PCI bus). When calling port detach on one
eth device it is required that all eth devices belonging to the
same rte device have been closed in advance, then the rte device
itself can be removed/detached.
This commit implements this requirement implicitly by adding a
remove callback to struct rte_pci_driver.
The new behavior can be demonstrated in testpmd.
First we attach a representor 0 using PCI address 0000:08:00.0
testpmd> port attach  0000:08:00.0,representor=[0]
Attaching a new port...
EAL: PCI device 0000:08:00.0 on NUMA socket 0
EAL:   probe driver: 15b3:1013 net_mlx5
Port 0 is attached.
Done
Port 1 is attached.
Done

Port 0 is the master device (PF) - an ethdev of the PCI address.
Port 1 is representor 0 - another ethdev (representing a VF) using the
same PCI address. Next we detach port 1
testpmd> port detach 1
Removing a device...
Port 0 is closed
Port 1 is closed
Now total ports is 0
Done

Since port 0 has been implicitly closed we cannot act on it anymore.
testpmd> port stop 0
Invalid port 0

42603bbdb5 net/mlx5: release port on close
With the introduction of representors several eth devices are using
the same rte device (e.g. a PCI bus). It is therefore required to
release the eth device resources during an eth device close operation
rather than during an rte device removal (detach) operation.
In current version many PMDs are still releasing the eth device as
part of the rte device removal. In order to allow a smooth transition
for all PMDs to behave correctly an ethdev flag RTE_ETH_DEV_CLOSE_REMOVE
is used. When this flag is set it indicates to rte_eth_dev_close() to
call rte_eth_dev_release_port(), so the port is freed during the close
operation.

206254b7dc net/mlx5: allow multiple probing for representor
Implement probing of a rte device multiple times, see [1].
Set PCI driver RTE_PCI_DRV_PROBE_AGAIN flag to enable multiple probing
of the PCI device by the PCI common driver.
Consecutive probing requests with a devargs string may contain
repetitive master and representors devices for which eth device should
be created only once. In case an eth device already exists - silently
ignore it.

2466364115 net/mlx5: fix flow tunnel handling
Both rte_flow and mlx5_flow redundantly have item flags. And it is not
properly set in the code. This causes wrong tunnel flag handling. A
rte_flow can have multiple expanded device flows if the flow has an RSS
action. Therefore, mlx5_flow should have the layers field.
