( https://gerrit.osmocom.org/12961 ) Change subject: Rewrite Packet Uplink IA Rest Octets for MBA ...................................................................... Rewrite Packet Uplink IA Rest Octets for MBA Use bitvec_set_*() directly without external write pointer tracking to simplify the code. This is part of IA Rest Octets (3GPP TS 44.018 §10.5.2.16) which is the last part of the message so it should not interfere with the rest of encoding functions. That's partially based on reverted commit 93d947f5e8a30acc9250c124bf9d5bb6a8863526.
