From 04bbb0a87e3acd75cb4c6dac6876160758a9614d Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Sat, 27 May 2023 12:15:47 +0200 Subject: [PATCH] batman-adv: Drop support for kernel < 5.15 OpenWrt master is no longer providing any kernels older than 5.15. Just drop the compat-hacks/patches for older kernels to make it easier to maintain the package.
