While tuning the number of instances of the functional blocks, the configuration may exceed the maximum number of queues that the NICs support. When this happens, the error message in the log is not informative. For example: Ethdev port_id=0 nb_rx_queues=43 > 8 Main/0 2024-06-25 17:07:22 ERR init_iface(back): failed to configure interface (errno=22): Invalid argument This commit identifies the problem and gives a helpful error message: Main/0 2024-06-25 17:38:22 ERR check_if_queues(back): the current configuration requires 43 RX queues, but the interface supports at most 8 RX queues. It may be possible to reduce the number of instances of the GK or GT functional block to reduce the number of queues. If not, more capable NICs are needed. Main/0 2024-06-25 17:38:22 ERR init_iface(back): interface doesn't support a critical hardware capability (errno=28): No space left on device This commit closes #620.
