tunnel: add geneve support
This patch extends the tunnel metadata object to define geneve tunnel
specific configurations:
table netdev x {
tunnel y {
id 10
ip saddr 192.168.2.10
ip daddr 192.168.2.11
sport 10
dport 20
ttl 10
geneve {
class 0x1010 opt-type 0x1 data "0x12345678"
class 0x1020 opt-type 0x2 data "0x87654321"
class 0x2020 opt-type 0x3 data "0x87654321abcdeffe"
}
}
