[ovs-dev] [PATCH] datapath: Update for changes in 2.6.39-rc1

[Simon Horman]

Update for flowi4 and ip_route_output_flow() changes
in 2.6.39-rc1.

Signed-off-by: Simon Horman <horms at verge.net.au>

Compile tested only

It is not immediately obvious to me how these updates
can be achieved using backwards-compatibility macros.
I am open to suggestions.
