Hi
More complete review

For 
+                proto_tree_add_text(nlri_tree, tvb, offset, length,
+                        "Unknown data, length = %d bytes.", length);
+                expert_add_info_format(pinfo, nlri_tree, &ei_bgp_ls_error,
+                        "Unknown data in Link-State Link NLRI!");
there is a new function proto_expert_info (it buil be add expert info and hf)

There is a lot of error when using checkhf/API tools

There is also clang warning
