[SRU][F][PATCH 0/1] net: openvswitch: fix misuse of the cached connection on tuple changes

[Frode Nordahl]

Buglink: https://launchpad.net/bugs/1967856

SRU Justification:

[Impact]

Users of Open vSwitch will not be able to upgrade to v2.16.0 or newer
until this long standing kernel bug has been fixed.

[Fix]

* 6bb3c77c74f5de28c78c74ef23af4c63e06e881e "net: openvswitch: fix
misuse of the cached connection on tuple changes"

[Test Plan]

A reproducer has been attached to the bug and can be executed with
the OVS system testsuite.

[Where problems could occur]

The regression potential can be considered as low because:
- The calls added in the openvswitch kernel datapath code would
  prior to Open vSwitch 2.16.0 have been initiated from the
  userspace code and by chance concealed this bug.
- After an optimization done in 2.16.0 the kernel bug was
  revealed and these calls now must be made from the kernel
