Change subject: Use Timing Advance Index in UL assignments
......................................................................
Use Timing Advance Index in UL assignments
Write TAI (if available) when generating Rest Octets for UL
Assignment. This should not affect actual PCU behavior because TAI is
not yet supported by upper layers but we have to adjust corresponding
tests anyway.
That's updated version of reverted commit.
