Failure to add offloaded policy will cause to the following
error once user will try to reload driver.
Unregister_netdevice: waiting for eth3 to become free. Usage count = 2
This was caused by xfrm_dev_policy_add() which increments reference
to net_device. That reference was supposed to be decremented
in xfrm_dev_policy_free(). However the latter wasn't called.
unregister_netdevice: waiting for eth3 to become free. Usage count = 2
leaked reference.
