api: fix trace_plugin_msg_ids segv in trace dump
With 'api-trace { on }' in startup.conf, running 'api trace dump' in vppctl was causing VPP to seg fault. vl_msg_print_trace() was calling m->endian_handler() without checking whether its null. Checking if its non-null prevents a crash, but the trace dump prints the message IDs for trace_plugin_msg_ids in network byte order. There is an auto-generated endian function for that message. Set it on the call to vl_msg_api_config() for trace_plugin_msg_ids so the IDs will be printed in host byte order in trace dump output. Type: fix Fixes: fe45f8f5 Signed-off-by: Matthew Smith <mgsmith@netgate.com> Change-Id: I0ab463985e9a983155feba13ac4eb99ab883ace6
