From d7913271649efb2d62cb3a93e81269ac6916c4cd Mon Sep 17 00:00:00 2001 From: Neels Hofmeyr Date: Wed, 3 Apr 2019 18:07:27 +0200 Subject: add osmo_bssap_tlv_parse2() for multiple identical T In BSSMAP messages, at least the Cell Identifier IE can appear more than once. We have tlv_parse2() which allows decoding into an array of tlv_parsed to cleanly handle multiple occurences. Hence add osmo_bssap_tlv_parse2() which supports multiple occurences. An alternative would be to directly call tlv_parse2() with gsm0808_att_tlvdef() when multiple T occurences are needed, and I'm not really sure why osmo_bssap_tlv_parse() exists in the first place. But because it does, add a similar definition that is capable of handling multiple IEs with identical Tag discriminator.
