Hi Hangbin,
[auto build test ERROR on ipsec/master]

In commit d77e38e612a0 ("xfrm: Add an IPsec hardware offloading API") we
make xfrm_device.o only compiled when enable option CONFIG_XFRM_OFFLOAD.
But this will make xfrm_dev_event() missing if we only enable default XFRM
options.
So when we set down and unregister an interface with IPsec on it.
