[Intel E810-CAM1] RDMA test failing on Windows Server 2025

[Siddick]

OS : Windows Server 2025

Adapter : Intel E810-CAM1 [Intel(R) Ethernet Controller E810-C for SFP]

Activated RDMA (iWarp) on above adapter. While testing RDMA we are getting error message that underlying adapter is RoCE (screenshot below).

Anyone has come across this issue ? Any recommendation to correct this problem ?
