This patch adds the following limitations to the mlx5 PMD guide:
- With HW Steering and E-Switch enabled, transfer proxy port must
be started before any port representor.
- With HW Steering and E-Switch enabled, all representors
must be stopped before transfer proxy port is stopped.
Documentation of mlx5 PMD's implementations of
rte_eth_dev_start() and rte_eth_dev_stop() is updated accordingly:
- rte_eth_dev_start() returns (-EAGAIN) when transfer proxy port
cannot be started.
- rte_eth_dev_stop() returns (-EBUSY) when port representor
cannot be stopped.
