Subject: net/sched: act_tunnel_key: Add extack message for offload failure
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=ee367d44b93664feaeea739c1324e914817be6f5;p=linux.git

net/sched: act_tunnel_key: Add extack message for offload failure

For better error reporting to user space, add an extack message when
tunnel_key action offload fails.

Currently, the failure cannot be triggered, but add a message in case
the action is extended in the future to support more than set/release
modes.
