oops, i am sorry. i did not read all the follow-ups before answering
your message...

the update of both DL and UL TBFs seems to be a good solution.


in the function above you wrote this comment:

|* TODO: There could be multiple DL and UL TBFs and we should
* have a proper way to link all the related TBFs so we can do
* a group update.

how can we have multiple TBFs for a single direction? i don't see anything like this in the specs.
