Shouldn't this goto skip setting the bits in tcs->slots?
No, we overwrite what we found with this new data.

Would be nice to remove this duplicate condition somehow. Maybe a goto?
I would return instead of the break earlier instead of this here.

find_match() above didn't check for tcs->cmd_addr. Does this ever happen
to fail?
Not allocated for active TCSes. I should be checking for it there as
well. Not sure how I didnt see a failure.
Ah, this function is never called for active tcs which would have the
tcs->cmd_addr to be NULL. I dont need this check.
