gue: Receive side for Generic UDP Encapsulation
This patch adds support receiving for GUE packets in the fou module. The fou module now supports direct foo-over-udp (no encapsulation header) and GUE. To support this a type parameter is added to the fou netlink parameters. For a GUE socket we define gue_udp_recv, gue_gro_receive, and gue_gro_complete to handle the specifics of the GUE protocol. Most of the code to manage and configure sockets is common with the fou. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
