Original GitHub issue: https://github.com/deepseek-ai/DeepEP/issues/764

Hello,
In DeepEP v1, there was a PR (https://github.com/deepseek-ai/DeepEP/pull/564) ensuring compatibility with NVSHMEM versions 3.5 and later, which was merged into the master branch at the time. However, the ibgda implementation currently merged into the legacy branch (following the v2 update) is missing the changes from that PR, rendering it incompatible with newer versions of NVSHMEM. Is there a specific reason for this?
