Subject: [PATCH net-next 4/6] netlink: specs: rt-route: describe lwtunnel IP options
Date: Thu, 17 Sep 2026 14:35:36 +0800 [thread overview]
Message-ID: <20260917-ynl_rt_encap-v1-4-fbbe6e680571@kylinos.cn> (raw)
In-Reply-To: <20260917-ynl_rt_encap-v1-0-fbbe6e680571@kylinos.cn>
From: Hangbin Liu <liuhangbin@kylinos.cn>
Replace binary opts in lwtunnel-ip and lwtunnel-ip6 with a nested
lwtunnel-ip-opts set. Add attribute sets for geneve, vxlan, and erspan
IP options to match linux/lwtunnel.h.
