Tested on regular OpenShiftSDN AWS IPI, verified dispatcher.d/99-vsphere-disable-tx-udp-tnl created but not activated on AWS as expected.

Upgrade from 4.7.0-0.nightly-2021-05-05-092347 to 4.8.0-0.nightly-2021-05-06-210840

Install vsphere upi with nightly build 4.7.0-0.nightly-2021-05-05-092347 in VMC, where:
- "platform:none" filed in install-config.yaml
- hardware version is 15

After installation is completed, checked all master/worker nodes:
tx-udp_tnl-segmentation: on
tx-udp_tnl-csum-segmentation: on

Then upgrade to 4.8.0-0.nightly-2021-05-06-210840
$ ./oc get clusterversion
NAME      VERSION                             AVAILABLE   PROGRESSING   SINCE   STATUS

$ ./oc get clusterversion

Checked again on nodes after upgrade, all have below options:
tx-udp_tnl-segmentation: off
tx-udp_tnl-csum-segmentation: off
