Cherry-pick request (LaunchPad bug #1860986)

[Kelsey Skunberg]

Hi Maxime,

I submitted the requested patch to the mailing list with the subject line :

[X/B/E/F][PATCH 0/2] openvswitch: Same tcp session encapsulated with
different udp src port for ovs vxlan tunnel

and can be found at:

https://lists.ubuntu.com/archives/kernel-team/2020-May/109666.html

Please refer to the above mailing list thread to review responses and progress.

I appreciate the details you provided in the bug report! I'm including
some information on how to submit a patch to the kernel mailing list
as this can help make sure the patches you want back ported are not
missed and reviewed faster.

Thanks Maxime! Have a great weekend. :)
