    Description

      We're allowed to start at a non-aligned page offset in the first fragment and end at a non-aligned page offset in the last fragment.

      Currently the first fragment is not considered. So it's possible to start on a non-aligned page boundary and consider that there is a gap in the transmit buffer, which is not correct.
