During backporting, if the fixes or stable tag are missing,
it usually requires some investigation by stable maintainer
as to why.
The presence of a fixes tag may be known from whether the
originating release of the issue is printed at the end of the
line but with variable line lengths and nested partial fixes
it doesn't catch the eye.
When there are a large amount of commits, adding an aligned column
indicating the presence of a fixes tag beside the stable one makes
it easier to quickly see the patches requiring further investigation.

When the HW finishes to consume the guest Rx descriptors, it creates a
CQE in the CQ.
The mlx5 driver arms the CQ to get notifications when a specific CQE
index is created - the index to be armed is the next CQE index which
should be polled by the driver.
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.

When all the virtqs works with poll mode, the event mechanism should not

The driver didn't take it into account and crashed in the above case.
Do not configure event interrupt when all the virtqs are in poll mode.

The problem occurred when workaround that makes soname two digits
applied. With this change for the ABI version "20.0.1" the experimental
library version become ".so.2001".
After workaround removed in ABI version 21.0, the experimental library
version will become ".so.210".
"2001" is bigger value than "201" although it is a previous version of
the library version, this can break the version comparisons.
To fix this, introducing a temporary sub level versioning for the
experimental libraries, so that minor version comparison will continue
to work.
After change experimental libraries will follow below versioning:
DPDK version ABI version soname library name
------------ ----------- ------ ------------
DPDK 19.11 20.0 .so.0.200 .so.0.200
DPDK 20.02 20.0.1 .so.0.200.1 .so.0.200.1
DPDK 20.05 20.0.2 .so.0.200.2 .so.0.200.2
DPDK 20.11 21.0 .so.0.210 .so.0.210
DPDK 21.02 21.1 .so.0.211 .so.0.211
Note: After workaround removed in DPDK 20.11 and soname switch back to
single digit this patch won't work and needs to be updated.
