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.
