Subject: [RFC net-next 05/14] net: core: rename netif_receive_generic_xdp() to do_generic_xdp_core()
Date: Wed, 18 Dec 2019 17:10:41 +0900 [thread overview]
Message-ID: <20191218081050.10170-6-prashantbhole.linux@gmail.com> (raw)
In-Reply-To: <20191218081050.10170-1-prashantbhole.linux@gmail.com>
From: Jason Wang <jasowang@redhat.com>
In skb generic path, we need a way to run XDP program on skb but
to have customized handling of XDP actions. netif_receive_generic_xdp
will be more helpful in such cases than do_xdp_generic.
This patch prepares netif_receive_generic_xdp() to be used as general
purpose function by renaming it.
