Subject: [RFC net-next 02/18] net: core: rename netif_receive_generic_xdp() to do_generic_xdp_core()

From: Jason Wang <jasowang@...hat.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.
