[PATCH v3 00/9] net/mlx5: per-queue Tx rate limiting via packet pacing

[Vincent Jardin]

Hi Stephen,

> mlx5_get_queue_rate_limit() doesn't bounds-check queue_idx before
> array access (the ethdev layer does, but the set path checks it
> too - inconsistent).

the fix in v4 goes in another direction: the redundant check was removed
from the setter as well, not added to the getter.

Both rte_eth_set_queue_rate_limit() and rte_eth_get_queue_rate_limit()
in the ethdev layer validate queue_idx >= nb_tx_queues before calling
the driver op. The driver callbacks can therefore assume this
precondition is met.

In v4, neither mlx5_set_queue_rate_limit() nor
mlx5_get_queue_rate_limit() checks queue_idx bounds, ethdev is the
single validation point for both.

Best regards,
  Vincent
