From dfcc0ff5d2bf6eb7c6ad7621c61c896e69ff8103 Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Wed, 18 Jan 2023 20:44:56 +0100 Subject: [PATCH] bpf-headers: fix use of netlink.h header netlink.h header have NL_SET_ERR_MSG_MOD that is tied to kmods. We don't need kmods on bpf tools and this cause compilation error if the header is included. Fix it by dropping NL_SET_ERR_MSG_MOD.
