geneve: add GRO hint output path
If a geneve egress packet contains nested UDP encap headers, add a geneve
option including the information necessary on the RX side to perform GRO
aggregation of the whole packets: the nested network and transport headers,
and the nested protocol type.
Use geneve option class `netdev`, already registered in the Network
Virtualization Overlay (NVO3) IANA registry:
https://www.iana.org/assignments/nvo3/nvo3.xhtml#Linux-NetDev.
To pass the GRO hint information across the different xmit path functions,
store them in the skb control buffer, to avoid adding additional arguments.
