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.

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.

datapath: Drop constness of datapath pointers.
A few places marked struct datapath pointers as const since they
didn't expect to make modifications. However, when compiled with
lockdep the datapath mutex pointer is passed to lockdep_is_held(),
which has a non-const argument. That provoked warnings about
casting away the const, so this drops the const from the original
pointers.

If a vport is a virtual device then it doesn't have a system ifindex.
We currently return the ifindex of the bridge device in this situation
but that's somewhat misleading, so this replaces it with 0. Nothing
actually reads the ifindex for devices other than the bridge device,
so this doesn't have a functional change.

free_buckets() is only called in places where the lifetime of its

neither can the buckets, so it is safe to directly free them.
sparse complains if the pointer is directly dereferenced and lockdep

datapath: Add owner to file_operations declaration.
It's currently possible for operations on our character device to
be still running when we unload the module. This will result in
an oops when the executing code is suddenly freed. The chrdev
code has a way to avoid this by taking a reference on the module
every time the device is opened, which means that we can't be
unloaded as long as there is an open file descriptor and therefore
the possibility of an operation. However, our file_operations
structure doesn't include an owner member, which prevents this
mechanism from working. This adds one.

In a few places, when creating a new vport we also need to allocate
some memory for configuration that can change. This data is protected
by RCU but we directly access the memory when initializing it. This
is fine, since the vport has not yet been published and we use the
apropriate memory barriers when doing so. However, it makes tools
like sparse unhappy and is also asymmetric since we use RCU to
dereference the pointers but not to assign them. This cleans that
up somewhat by initializing the memory first and then using RCU
to assign it, which makes everyone happy.

the local port always exists and never changes as long as the

There are a few places where we have two levels of RCU protected
data to allow the second level to change independently of the
first. Although the two pieces are independent, they have the
same users and lifetime of the first level always exceeds that
of the second level. This means that we can directly free the
second level when it is safe to free the first. This implies
that we directly access RCU-protected data, which is generally
not allowed. There are no locks to check, so none of the normal
RCU functions apply. Instead, this adds an explicit cast.

tunnel: Drop spinlock around cache free.
We hold a spinlock when freeing the cache, since you're generally
supposed to do that when writing to RCU protected data. However,
there's really no point in doing that here because the port has
already been removed from both the transmit and receive side
data structures and we've waited for an RCU grace period. In
addition, we're about to free the port itself, which contains the
spinlock and will be in trouble if anyone else is trying to
access it. For clarity, drop the spinlock.

datapath: Fix table sparse annotations.
Several of the pointers in table.c were missing the correct
__rcu annotation and the pointer type in the actual declaration
of struct tbl was incorrect, so this fixes that. It also adds
usage of rcu_dereference() to access an RCU protected pointer,
which is not strictly correct since an update side lock should
be held. However, since the table is used in different pieces
of code and therefore different locks are used it is difficult
to know which lock to check without threading the information
though, which is ugly. Since other places in table.c have this
same problem and this code should go away in the future it is
left as is.
