Description

While executing PCU_Tests_SNS.TC_sns_add or TC_sns_del, we are seeing the following error message on stderr of osmo-pcu (using gprs_ns2):

Error during TLV Parse in [L2]> 0d 04 82 04 d2 17 05 88 7f 00 00 01 59 da 00 01  (gprs_ns2.c:881)
Error during TLV Parse in [L2]> 11 04 82 04 d2 18 05 88 7f 00 00 01 59 d9 00 01  (gprs_ns2.c:881)
Error during TLV Parse in [L2]> 0e 04 82 04 d2 19 05 88 7f 00 00 01 59 d9 00 c8  (gprs_ns2.c:881)

First of all, the question is whether those errors are errors in NS2 or erors in our TTCN3 tests.

Secondly, why are those TLV parsing errors written to stderr without any prefix? There's no subssystem/level/... printed in frot. Look at this example:

20201009144947177 DLNS DEBUG GPRS-NS2-VC[0x5634298c0e40]{UNBLOCKED}: Received Event UNITDATA (gprs_ns2_vc_fsm.c:647)
