A set of overlapping changes in macvlan and the rocker
driver, nothing serious.

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.
Then if we set down and unregister an interface with IPsec on it. there
will no xfrm_garbage_collect(), which will cause dev usage count hold and
get error like:
unregister_netdevice: waiting for <dev> to become free. Usage count = 4

Upon NETDEV_DOWN event, all xfrm_state objects which are bound to
the device are flushed.
The condition for this is wrong, though, testing dev->hw_features
instead of dev->features. If a device has non-user-modifiable
NETIF_F_HW_ESP, then its xfrm_state objects are not flushed,
causing a crash later on after the device is deleted.
Check dev->features instead of dev->hw_features.

When we do IPsec offloading, we need a fallback for
packets that were targeted to be IPsec offloaded but
rerouted to a device that does not support IPsec offload.
For that we add a function that checks the offloading
features of the sending device and and flags the
requirement of a fallback before it calls the IPsec
output function. The IPsec output function adds the IPsec
trailer and does encryption if needed.

This patch adds all the bits that are needed to do
IPsec hardware offload for IPsec states and ESP packets.
We add xfrmdev_ops to the net_device. xfrmdev_ops has
function pointers that are needed to manage the xfrm
states in the hardware and to do a per packet
offloading decision.
