Just to be clear, I even want to rename the osmo-pfcp-tool since the current state is not really that of the old osmo-pfcp-tool in osmo-upf.git.
I plan to do so in a follow-up commit.

tbh I don't think it's worth it, since then we'd also need to spend time moving code around into differnet directiories, dropping/stripping out sutff not needed, etc.
From osmo-upf.git master afaik there's only an old osmo-pfcp-tool which was used as a base to add a lot more features which are kept in a separate WIP in branch (not really cleaned up) which Neels started and which I squashed with my own changes I did (again with an unstructured changeset while testing stuff).
So I think doing a proper import will take us a lot of time for no real good benefit.

This memset is not 0-initialization, it is the sync pattern. See the frame structure table in TS 48.060 section 5.3.2: the sync pattern consists of the first 16 bits being all zeros, then a single one. "Regular" data and speech frames have more sync pattern bits, but E-TRAU (or EDATA) frames have a reduced sync pattern. The other encoding functions under `osmo_trau_frame_encode` call `encode_sync16` helper, but because we have to produce the reduced sync pattern here, I am doing it directly.

Oops, I was setting the wrong bit - good catch! Fixed in the new patch revision.

Hello Jenkins Builder,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/c/libosmo-abis/+/38323?usp=email
to look at the new patch set (#2).
The following approvals got outdated and were removed:
Verified+1 by Jenkins Builder
Change subject: TRAU frame output EDATA: set sync pattern bits
......................................................................
TRAU frame output EDATA: set sync pattern bits
osmo_trau_frame_encode() for OSMO_TRAU16_FT_EDATA previously failed
to set the sync pattern bits in the generated output. Fix it.
