From f85861d6eb6ebc962bc710ac2d481536e6be7053 Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Sun, 16 Apr 2017 19:17:10 +0200 Subject: control_if: Add helper function for 'local execution' of control command Sometimes (particularly when testing), we may want to parse+execute an arbitrary control command simply form a string buffer, rather than from a msgb. Let's add a helper for that.
