TS 04.64 sec 7.2.1.1 LLGMM-ASSIGN specifies:
"""
If TLLI Old all 1's and TLLI New all 1's then TLLI Old and TLLI New are assigned, and TLLI New shall
be used when (re-)transmitting LLC frames. Both TLLI Old and TLLI New shall be accepted when received
from the peer. It shall be treated as a TLLI change according to subclause 8.3.2.
"""
