From 762148deb6be6925d17bd12f219f7385e1402439 Mon Sep 17 00:00:00 2001 From: Paul Holzinger Date: Mon, 15 Mar 2021 10:45:24 +0100 Subject: Split libpod/network package The `libpod/network` package should only be used on the backend and not the client. The client used this package only for two functions so move them into a new `pkg/network` package. This is needed so we can put linux only code into `libpod/network`, see #9710.
