From: Christian Marangi Date: Wed, 18 Jan 2023 19:44:56 +0000 (+0100) Subject: bpf-headers: fix use of netlink.h header X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=dfcc0ff5d2bf6eb7c6ad7621c61c896e69ff8103;p=openwrt%2Fopenwrt.git 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.
