laforge gerrit-no-reply at lists.osmocom.orglaforge has submitted this change. ( https://gerrit.osmocom.org/c/libosmocore/+/21465 ) Change subject: ns2: Add log filtering by NSE/NSEI, fix NSVC filter on receive ...................................................................... ns2: Add log filtering by NSE/NSEI, fix NSVC filter on receive NSVC filtering was only implemented on sending messages, this also adds log_set_context() calls to ns2_recv_vc() Filtering by NSE is implemented similar to NSVC.
