From 901271e0403af638c224987c2a4e55cebade7e91 Mon Sep 17 00:00:00 2001 From: GhantaKrishnamurthy MohanKrishna Date: Thu, 19 Apr 2018 11:06:19 +0200 Subject: tipc: implement configuration of UDP media MTU In previous commit, we changed the default emulated MTU for UDP bearers to 14k. This commit adds the functionality to set/change the default value by configuring new MTU for UDP media. UDP bearer(s) have to be disabled and enabled back for the new MTU to take effect.
