From 0c65ef4fbbf3d3c1c4435f06db7648ab67935a19 Mon Sep 17 00:00:00 2001 From: Christian Svensson Date: Fri, 30 Dec 2022 21:27:10 +0100 Subject: net: Increase L2TPv3 buffer to fit jumboframes Increase the allocated buffer size to fit larger packets. Given that jumboframes can commonly be up to 9000 bytes the closest suitable value seems to be 16 KiB. Tested by running qemu towards a Linux L2TPv3 endpoint and pushing jumboframe traffic through the interfaces.
