[dpdk-dev] [PATCH v3 07/13] net/mlx5: switch to the shared Protection Domain

[Viacheslav Ovsiienko <viacheslavo@mellanox.com>]

The PMD code is updated to use Protected Domain from the
the shared IB device context. The Domain is shared between
all devices belonging to the same multiport Infiniband device.
If IB device has only one port, the PD is not shared, because
there is only ethernet device created over IB one.
