Cover letter [PATCH ipsec-next v1 0/5] Support PMTU in tunnel mode for packet offload

Changelog:
v1:
* Changed signature and names of functions which set and clear type_offload
* Fixed typos

Hi,

This series refactors the xdo_dev_offload_ok() to be global place for drivers to check if their offload can perform encryption for xmit packets.

Such common place gives us an option to check MTU and PMTU at one place.

Thanks
