Dear all

I would like to report an issue that I notice on window 11 recently update 

2025-02-07|4.1025.207.1|0xff0000|0|0|Intel Corporation|Intel Corporation|Intel(R) Connectivity Performance Suite|SWC\VID_8086&PID_ICPS&SID_0002

In windows update it is called 'Intel Corporation - SoftwareComponent- 4.1025.207.1

Once the service  'Intel Connectivity Network Service' it will clean up ipv6 flow table when ssl handshake started, does not matter which nic customer are using, intel or no-intel and wired or no -wired nic. 

while ipv6 flow table got clean up it cause serious problem of ECMP setup big cloud network and flow has been randomly send to different backend device after tcp handshake was established. 

the issue can be reproduce on windows 11 + Intel Connectivity Network Service (Intel Corporation - SoftwareComponent- 4.1025.207.1) with following reproduce script 

expected result is 100% 200 ok, 

but we see failed situation like below, once disable Intel Connectivity Network Service  the issue is gone
