This is fine, as long as we have 16 queues or less.
Otherwise, we need to fill the EXT_IID as well (only if bEXTIIDEn = 1).

Yes, correct. Will add the code for EXT_IID in the next version.

Also, don't we need to do this for query commands as well?
Or at least add a comment that the queue id for query command is 0.

Query commands would use the reserved queue whose id = 0.
I agree a comment should be added detailing this.
Will add in the next version.

Thanks,
Avri
