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

Leon Romanovsky (5):
  xfrm: delay initialization of offload path till its actually requested
  xfrm: simplify SA initialization routine
  xfrm: rely on XFRM offload
  xfrm: provide common xdo_dev_offload_ok callback implementation
  xfrm: check for PMTU in tunnel mode for packet offload
