Subject: Re: [PATCH net-next] net: ip6_gre: Give ERSPAN a fill_info link op

> In commit c706863bc890 ("net: ip6_gre: always reports o_key to
> userspace"), ip6gre and ip6gretap tunnels started reporting a TUNNEL_KEY
> output flag even if one was not configured at the device.
> 
> When an okey-less ip6gre or ip6gretap netdevice is created, it initially
> encapsulates the packets without okey. But any configuration change
> (even a non-change such as setting TOS to an already-configured value)
> then causes the okey flag from the reported configuration to be
> circulated back to actual configuration. From that point on, the device
> encapsulates packets with output key of 0.

> The intention was to implement this behavior for ERSPAN devices, not for

> fill_info callback. Add one.
