Change subject: bts: test for "logging filter l1-sapi"
......................................................................


Abandoned

Unfortunately, this test does not work anymore with the updated code in https://gerrit.osmocom.org/c/osmo-bts/+/15539.

f_pcu_data_req() does not cause the bts to set the log context anymore. To set the log context, we would need to have an uplink/downlink message received by/sent to the PHY. The testsuite uses osmo-bts-trx, which does not deal with sapi message types in the osmo-bts/src/osmo-bts-trx uplink related code (therefore the log context is not set; it would have worked with osmo-bts-sysmo, -octphy, -oc2g, -litecell).

I have looked into causing osmo-bts to send a downlink message to L1CTL from the testsuite. A good way to do this seemed to send the S13 information via RSL, which would then get sent to the L1CTL via BCCH, which also appears in the log. But then I realized, that this only gets sent the first time and I did not find an easy way to reset the connection and make the test send the message again.

Then I looked into using another L1CTL message, but for some reason the existing L1CTL tests like TC_deact_sacch are not working in my local setup, when running the testsuite outside of docker (and the way the docker images are structured, the test cycles are too long when first pushing the changes to the git server, then rebuilding the testsuite with a new docker image).

So all in all it seems that I'm spending too much time on this :\ abandoning this test.
