I see - it is being backported by kernel and also defined again by OVS. What do you recommend to fix this issue in case of my kernel version 3.10.0-54.0.1.el7.x86_64 on Red hat beta 7 where the function
Is backported.
Thanks,
Ashok

It looks like this function was backported to your kernel version, which is why you see the conflict. The OVS compatibility header checks for linux 3.12, and defines the function if you're running any earlier version.
