From aded3f6b9654b46ec85a84af4bc02d53663b4c0c Mon Sep 17 00:00:00 2001 From: Dario Binacchi Date: Fri, 2 Jun 2023 10:57:41 +0200 Subject: [PATCH] package/libmnl: remove dependency on kernel headers version As agreed in [1], now that the patch for including kernel headers has been applied upstream, we can remove the restrictions in Buildroot to avoid compilation failures. The patch is an adaptation of the one applied upstream.
