/* hack: in schedule_ue_spec, 3 bytes are "reserved" (this should be
* done better). An RLC AM entity may ask for only 2 bytes for
* ACKing and get a TBS of 32 bits and due to these 3 reserved bytes we may
* end up with only 1 byte left for RLC, which is not enough. This hack
* prevents the problem. To be done better at some point. If the function
* schedule_ue_spec is (has been) reworked, this hack can be removed.
* Dig for "TBS - ta_len - header_length_total - sdu_length_total - 3"
* in schedule_ue_spec.
