Subject: [PATCH net-next v2 0/3] net: tunnel: introduce noref xmit flows for tunnels

Currently, all xmit flows use dst_cache in a way that references
its dst_entry for each xmitted packet. These atomic operations
are redundant in some flows.

This patchset introduces new noref xmit helpers, and incorporates
them in the OpenVPN driver.

Changes in v2:
 - Fixed docstrings for dst_cache_get_ip4_rcu and dst_cache_steal_ip4
