[PATCH v3 0/3] ethdev: document special cases of port start and stop

[Dariusz Sosnowski]

This patch series attempts to address the special failure
cases of rte_eth_dev_stop() and rte_eth_dev_start().

In case of starting a port, If the port cannot be started and
start operation must be retried, PMDs might return (-EAGAIN)
to notify about such situation.

In case of stopping a port, If the port cannot be stopped
in the current state, PMDs might return (-EBUSY)
to notify about such situation.

These cases are addressed in ethdev API docs.
Testpmd is updated to allow users to manually retry start/stop operations.

v3:
- Allow to retry port stop in testpmd for all errors.
- Made error descriptions in the API more generic and
  moved specific error causes descriptions to PMD.

v2:
- Fixed documentation build.

Dariusz Sosnowski (3):
  net/mlx5: fix log level on failed transfer proxy stop
  net/mlx5: document E-Switch limitations with HWS in mlx5 PMD
  ethdev: document special cases of port start and stop
