From 5caf35a7e4bd573a22ff7ed0c686c1cf516eeaf0 Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Sat, 14 May 2016 18:07:12 +0200 Subject: refactor EDSP code into EDSP and EDSP-like parts No real code change, just moving code around heavily to decouple the EDSP specific parts from those we can reuse for EDSP-like protocols.
