2014-11-06gue: Add infrastructure for flags and optionsTom Herbert1-5/+95
Add functions and basic definitions for processing standard flags, private flags, and control messages. This includes definitions to compute length of optional fields corresponding to a set of flags. Flag validation is in validate_gue_flags function. This checks for unknown flags, and that length of optional fields is <= length in guehdr hlen.

2014-10-04gue: Receive side for Generic UDP EncapsulationTom Herbert1-0/+23
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>
