drivers/crypto: fix build with make 4.3

In the check for the version of intel-ipsec-mb library,
there is a backslash in front of the #include.
This backslash is for escaping the hash sign parsed as
a number sign in make.

Since make-4.3, escaping is not required for the number sign.
As a consequence, it resolves now to '\#':

syntax error near unexpected token `|'
`grep -e "IMB_VERSION_STR" \#include <intel-ipsec-mb.h> | cut -d'"' -f2'

`grep -e "IMB_VERSION_NUM" \#include <intel-ipsec-mb.h> | cut -d' ' -f3'

The mlx5 driver configured the kernel driver to send notification to the
guest callfd in the same time it arrives to the mlx5 driver.

It means that the guest was notified only for each first CQE in a poll
cycle, so if the driver polled CQEs of all the virtio queue available
descriptors, the guest was not notified again for the rest because
there was no any new cycle for polling.

Hence, the Rx queues might be stuck when the guest didn't work with
poll mode.

Move the guest notification to be after the driver consumes all the
SW own CQEs.
By this way, guest will be notified only after all the SW CQEs are
polled.

Also init the CQ to be with HW owner in the start.

4 years agonet/mlx5: fix layer flags missing in metadata
Suanming Mou [Thu, 20 Feb 2020 13:53:43 +0000 (15:53 +0200)]
net/mlx5: fix layer flags missing in metadata

Metadata suffix subflow inherits the RSS needed hash_fields from the
prefix subflow as the suffix subflow only has the tag match item unable
to generate the full original hash_fields for RSS action.

Unfortunately, hash_fields will only be generated if flow has RSS
action. So it means the prefix flow won't generate the hash_fields as
the RSS action has been split to the suffix flow.

Copy the layer flags from prefix subflow to suffix subflow to help the
suffix subflow to generate the correct hash_fields itself.

net/bnxt: fix race condition when port is stopped

Fix a race condition between port stop and error recovery task. When io
forwarding is not started on Stingray devices, driver will not receive
the async event from FW when there is a FW reset. While exiting testpmd,
as part of port stop driver sees this event and this in turn causes a
race between port stop and error recovery task.

Fixed this by ignoring the fatal/non-fatal async event from FW while
stopping port.
