This patch adds support to configure foo-over-udp (FOU) and Generic
UDP Encapsulation for IPIP and sit tunnels. This configuration allows
selection of FOU or GUE for the tunnel, specification of the source and
destination ports for UDP tunnel, and enabling TX checksum. This
configuration only affects the transmit side of a tunnel.
Example:
ip link add name tun1 type ipip remote 192.168.1.1 local 192.168.1.2 \
ttl 225 encap gue encap-sport auto encap-dport 9999 encap-csum
This would create an IPIP tunnel in GUE encapsulation where the source
port is automatically selected (based on hash of inner packet) and
checksums in the encapsulating UDP header are enabled.

Allow to print particular link type usage by:
ip link help [TYPE]
Currently to print usage for some link type it is needed
to use the following way:
ip link { add | del | set } type TYPE help

This patch allows to manage ip tunnels via the interface ip link.
The syntax for parameters is the same that 'ip tunnel'.
It also allows to display tunnels parameters with 'ip -details link' or
'ip -details monitor link'.
