Jesse Gross 81e5d41d7e openvswitch: Fix checksum update for actions on UDP packets.
When modifying IP addresses or ports on a UDP packet we don't
correctly follow the rules for unchecksummed packets.  This meant
that packets without a checksum can be given a incorrect new checksum
and packets with a checksum can become marked as being unchecksummed.
This fixes it to handle those requirements.

Ben Pfaff 651a68ea2c openvswitch: Honor dp_ifindex, when specified, for vport lookup by name.
When OVS_VPORT_ATTR_NAME is specified and dp_ifindex is nonzero, the
logical behavior would be for the vport name lookup scope to be limited
to the specified datapath, but in fact the dp_ifindex value was ignored.
This commit causes the search scope to be honored.

Ben Pfaff 77676fdbd5 openvswitch: Fix multipart datapath dumps.
The logic to split up the list of datapaths into multiple Netlink messages
was simply wrong, causing the list to be terminated after the first part.
Only about the first 50 datapaths would be dumped.  This fixes the
problem.

Dan Carpenter f0a98ae8db openvswitch: small potential memory leak in ovs_vport_alloc()
We're unlikely to hit this leak, but the static checkers complain if we
don't take care of it.

Jesse Gross ccb1352e76 net: Add Open vSwitch kernel components.
Open vSwitch is a multilayer Ethernet switch targeted at virtualized
environments.  In addition to supporting a variety of features
expected in a traditional hardware switch, it enables fine-grained
programmatic extension and flow-based control of the network.
This control is useful in a wide variety of applications but is
particularly important in multi-server virtualization deployments,
which are often characterized by highly dynamic endpoints and the need
to maintain logical abstractions for multiple tenants.

The Open vSwitch datapath provides an in-kernel fast path for packet
forwarding.  It is complemented by a userspace daemon, ovs-vswitchd,
which is able to accept configuration from a variety of sources and
translate it into packet processing rules.

See http://openvswitch.org for more information and userspace
utilities.
