Subject: [PATCH v2 0/1] i40e: additional safety check

From: Gregory Herrero <gregory.herrero@...cle.com>


On code inspection, I realized we may want to check ring_len parameter
against hardware specific values in i40e_config_vsi_tx_queue() and
i40e_config_vsi_rx_queue().

v2:
- make i40e_get_max_num_descriptors() 'pf' argument const.
- reword i40e_get_max_num_descriptors() description.
- modify commit description to explain potential behavior change.

Gregory Herrero (1):
  i40e: validate ring_len parameter against hardware-specific values.
