[dpdk-dev] [PATCH v3 1/2] net/mlx5: fix return value of start operation

[Olivier Matz]

On error, mlx5_dev_start() does not return a negative value
as it is supposed to do. The consequence is that the application
(ex: testpmd) does not notice that the port is not started
and begins the rxtx on an uninitialized port, which crashes.

v2->v3:
- rebase on top of head
  The commit is much smaller after
  c7bf62255edf ("net/mlx5: fix handling link status event")

For backport, prefer the v2.
