Currently tun-info options pointer is used in few cases to

ip_tunnel_info_opts() API without using the pointer. Following
patch removes the redundant pointer and consistently make use

Hi everyone,
I am trying to use iperf over a veth pair. while iperf is pleased (it
reports a suspicious very high bandwidth), according to tcpdump, no
traffic is going via the veth pair.
Also 'ping -I' refuses to send a ping via my veth ('destination is
unreachable' iirc).

- Patchset provides a general and easy to use abstraction to extend ss later

The prospected output formatters and ss do share type declarations like

those declarations in ss_types.h. Potential future declarations shall

This patch creates a central formatter module that acts as a kind of
switch. From there, more specific handler modules for the certain output
