Subject: [Intel-wired-lan] [PATCH iwl-next v5 05/13] idpf: add 4-byte
completion descriptor definition

From: Michal Kubiak <redacted>

In the queue-based scheduling mode, Tx completion descriptor is 4 bytes
comparing to 8 bytes in flow-based.
Add definition for it and allocate the corresponding amount of memory for
the descriptors during the completion queue creation.
This does not include handling 4-byte completions during Tx polling, as for
now, the only user of QB will be XDP, which has its own routines.
