This is a good reason (fixing a bug) and should be mentioned in the
commit description.  Do we have more detailed information on this?

This is an optimization and not entirely mandatory.  This is the only
thing I thought this patch was addressing (the commit message was not
very descriptive, so I could only assume).  At this stage (ie. close to
the merge window), I didn't want to assume the risk of a change just for
to optimize things a bit.  And, since I had my doubts about the block_tx
value, I decided not to include it.

Okay, once I get the answer from the firmware team about the block_tx
value, I'll fix up this patch and apply it.

Thanks for the explanantions.
