[Impish][OEM-5.14][SRU][PATCH 0/2] Fix kselftests/net/test_vxlan_under_vrf.sh

[Po-Hsu Lin]

[Impact]
test_vxlan_under_vrf.sh in the net category of ubuntu_kernel_selftests
will fail on 5.13 kernel with:

  # selftests: net: test_vxlan_under_vrf.sh
  # Checking HV connectivity [ OK ]
  # Check VM connectivity through VXLAN (underlay in the default VRF) [FAIL]
  not ok 1 selftests: net: test_vxlan_under_vrf.sh # exit=1

[Fix]
* e7e4785f selftests: net: test_vxlan_under_vrf: fix HV connectivity test
* b50d3b46 selftests: test_vxlan_under_vrf: Fix broken test case

The first patch (e7e4785f) can be cherry-picked to Impish 5.13 and
F-oem-5.14.

Note that this test is not failing on F-oem-5.14, but it's better to
have it applied to reduce the maintenance cost.

After the first patch was applied, we will need the second patch on
Impish 5.13 to solve the another failure, which we made it an expected
failure (XFAIL) with SAUCE patches:
  Check VM connectivity through VXLAN (underlay in a VRF) [XFAIL]

The second patch (b50d3b46) can be cherry-picked to Impish 5.13 but
must be applied with -C2 due to our SAUCE patches. F-oem-5.14 has
already got this one applied.

[Test]
With the patched test_vxlan_under_vrf.sh test, it can pass on Impish
5.13 and F-oem-5.14 without any issue:
  Checking HV connectivity [ OK ]
  Check VM connectivity through VXLAN (underlay in the default VRF) [ OK ]
  Check VM connectivity through VXLAN (underlay in a VRF) [ OK ]

[Where problems could occur]
Change limit to test cases, should not have any real impact to any
kernel functions. But if these fixes are incorrect we will see
failures in our regression-testing report. The worst scenario is
getting false-negative results.
