Use TCA_POLICE_RATE64 if the rate cannot be expressed using 32bits.
This breaks the 32Gbps barrier. The new barrier is ~4Tbps caused by
netdev's API expressing kbps rates using 32-bit integers.

Current issues with Flow API:
* OVS calls offloading functions regardless of successful
flow API initialization. (ex. on init_flow_api failure)
* Static initilaization of Flow API for a netdev_class forbids
having different offloading types for different instances
of netdev with the same netdev_class. (ex. different vports in
'system' and 'netdev' datapaths at the same time)
Solution:
* Move Flow API from the netdev_class to netdev instance.
* Make Flow API dynamic, i.e. probe the APIs and choose the
suitable one.
Side effects:
* Flow API providers localized as possible in their modules.
* Now we have an ability to make runtime checks. For example,
we could check if particular device supports features we
need, like if dpdk device supports RSS+MARK action.

netdev vports are backed by actualy netdev at the kernel
level, so they can use the common netdev-tc offloads interface
for flow offloading (if enabled).

Add a new API interface for offloading dpif flows to netdev.
The API consist on the following:
flow_put - offload a new flow
flow_get - query an offloaded flow
flow_del - delete an offloaded flow
flow_flush - flush all offloaded flows
flow_dump_* - dump all offloaded flows
In upcoming commits we will introduce an implementation of this
API for netdev-linux.

The only uses of 'af_inet_sock', in both drivers, were ioctls, so it seemed
like a good abstraction to write a function that just does such an ioctl,
and to factor out shared code into socket-util.

These headers don't really need datapath-protocol.h. connmgr.h indirectly
used "struct nlattr" from that header, so add a forward declaration. (The
next commit will remove use of struct nlattr entirely from that header,
since it is not really appropriate.)
Currently ovs is using device stats for Linux devices and count them
itself in other situations. This leads to overlap with hardware stats,
inconsistencies, etc. It's much better to just always count the packets
flowing through the switch and let userspace do any merging that it wants.
Following patch removes vport->get_stats() interface. vport-stat is changed
to use new `struct ovs_vport_stat` rather than rtnl_link_stats64.
Definitions of rtnl_link_stats64 is removed from OVS. dipf_port->stat is also
removed as aggregate stats are only available at netdev layer.

An upcoming commit will introduce another function that needs to convert
between rtnl_link_stats64 and netdev_stats, so it seemed best to just add
functions to do the conversion.
