From 2291a36008e197423a0f0414f6dcca4afa3ac4c1 Mon Sep 17 00:00:00 2001 From: Marek Gradzki Date: Mon, 20 Feb 2017 09:14:13 +0100 Subject: jvpp: remove unnecessary msg_id_base caching Jvpp code uses CRCs to obtain msg IDs. Checking api_main_t.msg_index_by_name_and_crc is enough to detect API mismatch. Calling vl_client_get_first_plugin_msg_id is not needed. Also fixes VPP-627.
