VXLAN: Support outer IPv4 Tx checksums by default
This change makes it so that if UDP CSUM is not specified we will default to enabling it. The main motivation behind this is the fact that with the use of outer checksum we can greatly improve the performance for VXLAN tunnels on devices that don't know how to parse tunnel headers.
