From e6fd398d61a9810d53a2a5a30294500718e43286 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Zbigniew=20J=C4=99drzejewski-Szmek?= Date: Mon, 5 Oct 2020 14:23:19 +0200 Subject: [PATCH] man: reword the descriptions of VXLAN DestinationPort= and PortRange= The usual: "empty string" is meaningless in this context. We are not assigning DestinationPort="". Just say "unset".
