Another way to solve this could have been to encode that length
as "length - 1"

True. I had pondered that, but felt that since changing q_len's type
didn't add any length to the structure and that it was less impactful
from a number-of-lines of code changed perspective, I'd opt for this
route.

Cavium, if you'd prefer this goes the route that Dave just mentioned,
please let me know and I can make a new patch against what's been
applied?

Thanks for fixing this and i think the current patch is fine.

You're welcome. And thanks for responding. So I'll leave things as they
are.
