From b09f4d0adb8364b3516c3a64e8238715887ffec8 Mon Sep 17 00:00:00 2001 From: Dave Barach Date: Mon, 15 Jul 2019 16:00:03 -0400 Subject: api: enable binary API event logging in vat Cleaned up a few instances of side-bet elog_string hash table usage. Elog_string handles that problem itself. Add cli commands to vat to initialize, enable/disable, and save an event log. Event logging at the same time in both vpp and vat yields a pair of event logs which can be merged by the "test_elog" tool.
