I don't see anything obvious in 3GPP TS 36.323 itself that says the format is different; does something in a later RFC specify something different?
Yep: I read the RFC the same way; There's an 'offset++' after the fetch of ts so I think the code is Ok. guint8 ts = tvb_get_guint8(tvb, offset) & 0x1f; proto_tree_add_uint(tree, hf_pdcp_lte_rohc_ts, tvb, offset, 1, ts); offset++; /* Large CID */ if (p_pdcp_info->large_cid_present) { offset = dissect_large_cid(tree, tvb, offset); } /* m */ proto_tree_add_item(tree, hf_pdcp_lte_rohc_m, tvb, offset, 1, ENC_BIG_ENDIAN); ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
