Subject: [RFC net-next 03/18] net: core: export do_xdp_generic_core()
Date: Tue, 26 Nov 2019 19:07:29 +0900 [thread overview]
Message-ID: <20191126100744.5083-4-prashantbhole.linux@gmail.com> (raw)
In-Reply-To: <20191126100744.5083-1-prashantbhole.linux@gmail.com>
From: Jason Wang <jasowang@redhat.com>
Let's export do_xdp_generic as a general purpose function. It will
just run XDP program on skb but will not handle XDP actions.
