This is merely a historical archive of years 2008-2021, before the migration to mailman3.
A maintained and still updated list archive can be found at https://lists.osmocom.org/hyperkitty/list/OpenBSC@lists.osmocom.org/.
Daniel Willmann dwillmann at sysmocom.deMany functions only ever deal with or return a UL or a DL TBF.
Explicitly change the type to reflect which TBF is used where.
