880 * Limits capabilities to those that are understood by the
881 * fail-safe PMD. This understanding stems from the fail-safe
882 * being capable of verifying that the related capability is
883 * expressed within the device configuration (struct rte_eth_conf).
885 * At least one probed sub_device:
887 * Uses values from the active probed sub_device
888 * The rationale here is that if any sub_device is less capable
889 * (for example concerning the number of queues) than the active
890 * sub_device, then its subsequent configuration will fail.
891 * It is impossible to foresee this failure when the failing sub_device
892 * is supposed to be plugged-in later on, so the configuration process
893 * is the single point of failure and error reporting.
895 * Uses a logical AND of RX capabilities among
896 * all sub_devices and the default capabilities.
897 * Uses a logical AND of TX capabilities among
898 * the active probed sub_device and the default capabilities.
899 * Uses a logical AND of device capabilities among
900 * all sub_devices and the default capabilities.
