From f53ab9328ad37c733d13e7f0886acf4a111898d0 Mon Sep 17 00:00:00 2001 From: Micael Karlberg Date: Thu, 21 Mar 2019 12:03:29 +0100 Subject: [snmp|agent] Handle new get-mechanism config Also streamlined the config storage. And corrected the store of the set_mechanism (in the snmp_agent_table). This is only used for debugging, but just the same.
