datapath: Treat GSO skbs as if they were fragments
In dp_output_control() UDP GSO skbs are split into fragments which are
passed to userspace. So the resulting flow set-up by the controller
(I am using ovs-vswitchd) is created based on a fragment. This means
that the UDP source and destination port of the flow is zero.
In order for the datapath to match the resulting flow flow_extract() needs
to treat UDP GSO skbs as if they are fragments. That is, set the UDP
source and destination port to 0.
A flow established for a UDP GSO skb with this change won't match any
subsequent non-GSO skbs, they will need to be passed to the controller and
a new flow established. But without this change no UDP GSO skbs will ever
match any flow.
I noticed this while using KVM using virtio with VhostNet and netperf's
UDP_STREAM test. The result was that the test sent ~5Gbit/s but only a
small fraction of that was received by the other side. Much less than the
1Gbit/s available on the physical link between the host (and guest) and the
machine running netserver. 100% of one of the host's CPUs was consumed, 50%
for the host and 50% for the guest. The host consumption was contributed
to largely by ovs-vswitchd.
With this change I get a much nicer result of a fraction under 1Gbit/s sent
and almost all packets ending up at the other end.

datapath: Fix double counting of packet stats for Linux devices.
The kernel augments stats for Linux devices that only provide 32-bit stats
with its own internal 64-bit counters. When doing this it takes the error
stats from the device but uses the packet and byte values from its local
counters. However, we were also taking the packet and byte counts from
the device, leading to double counting.

datapath: Use call_rcu() when deleting a datapath.
When deleting a datapath, we remove all of the vports and then immediately
free the datapath data structures. Since the vports are allowed to use
call_rcu() to free their data, it's possible for them to return immediately
while packet processing is still taking place. This breaks apart the dropping
of references and the freeing of the data using call_rcu() for protection.
This race cannot actually occur in practice since the last port to be
deleted is an internal device, which uses synchronize_rcu() itself
(implicitly through unregister_netdevice()). However, there is no
requirement that it must do this nor should there be.
