This series fixes some TxQ scheduling mode issues exposed by recent FW changes, as well as some issues reported by Sashiko.
Patch 1 prevents XDP from being enabled if queue based scheduling is not supported by the firmware. Patch 2 fixes a data race when accessing next_to_clean in IDPF_DESC_UNUSED. Patch 3 fixes a NULL ptr dereference in the Tx path when queue based scheduling is enabled, and also adds support to process both 4 and 8 byte completion descriptors to avoid timeouts in queue based scheduling mode.
