This Series make some cleanup in mlx5 PMD by removing useless code or non
working code.
This series apply on top of:
[PATCH 0/5] net/mlx5: enable/disable vPMD and some cleanups
Specifically on patch: net/mlx5: cleanup Rx ring in free functions
http://dpdk.org/dev/patchwork/patch/27303/
Nelio Laranjeiro (5):
net/mlx5: remove flow drop useless if branches
net/mlx5: remove pdentic pragma
net/mlx5: fix non working secondary process by removing it
net/mlx5: remove multiple drop RSS queues
net/mlx5: remove old MLNX_OFED 3.3 verification

Those two if statements are useless as there is a verification on the drop
field of the flow to jump to the end of the function just above.

Secondary process is a copy/paste of the mlx4 drivers, it was never
tested and it even segfault at the secondary process start in the
mlx5_pci_probe().
This makes more sense to wipe this non working feature to re-write a
working and functional version.
Fixes: a48deada651b ("mlx5: allow operation in secondary processes")

Can you please elaborate what is changed with MLNX_OFED 4.1?
Also how one can know his MLNX_OFED version?

Does this means multi process support for mlx5 broken with this patch?
If so features file and release notes should be updated if this won't be
fixed back in this release..
And what is special required for mlx5 secondary process support?

Hi Ferruh,
This is already documented in the NIC guides, see section "20.5.
Prerequisites" [1].

Hardware drop queues are supported since this version, before that, the flow
drop was handled by software queues not polled.

Currently the user has to download and install it to have a working PMD, the
NIC documentation provides the related information on where to get this
Mellanox OFED from their website. So the user knows which version of MLNX
OFED is installed in his system.

No currently the secondary process in mlx5 is not working at all. This is
only removing a non working code from the PMD.
> And what is special required for mlx5 secondary process support?
There is some work to make this secondary process work correctly, but as it
will be totally different, it does not make sense to keep a non working code
to replace it by a working one.
Concerning the release note and features, this new implementation is
expected in 17.11 same release as this patch.

I'll update the feature documentation in a v2 to remove the "Multiprocess
aware" from the feature list in this patch.
It will be added back with the new implementation.

Yes it is, Adrien is pushing some patch to the OFED community to make it
also pedantic.

This Series make some cleanup in mlx5 PMD by removing useless code or non
working code.
Changes in v2:
- update mlx5 feature list to remove the multi process awareness.
Nelio Laranjeiro (8):
net/mlx5: avoid reusing old queue's mbuf on reconfigure
net/mlx5: prepare vector Rx ring at setup time
net/mlx5: cleanup Rx ring in free functions
net/mlx5: remove flow drop useless if branches
net/mlx5: remove pdentic pragma
net/mlx5: fix non working secondary process by removing it
net/mlx5: remove multiple drop RSS queues
net/mlx5: remove old MLNX_OFED 3.3 verification

To use the vector, it needs to add to the PMD Rx mbuf ring four extra mbuf
to avoid memory corruption. This additional mbuf are added on dev_start()
whereas all other mbuf are allocated on queue setup.
This patch brings this allocation back to the same place as other mbuf
allocation.

Vector PMD returns buffers to the application without setting the pointers
in the Rx queue to null nor allocating them. When the PMD cleanup the ring
it needs to take a special care to those pointers to not free the mbufs
before the application have used them nor if the application have already
freed them.

Those two if statements are useless as there is a verification on the drop
field of the flow to jump to the end of the function just above.

To: dev, Ferruh Yigit; +Cc: Shahaf Shuler
Secondary process is a copy/paste of the mlx4 drivers, it was never
tested and it even segfault at the secondary process start in the
mlx5_pci_probe().
This makes more sense to wipe this non working feature to re-write a
working and functional version.
Fixes: a48deada651b ("mlx5: allow operation in secondary processes")
