[Proposal] Adding HybridEP compatibility with newer NVSHMEM versions #691
Description
On the main branch v1.x, there was runtime timeout when NVSHMEM modified the way default qpairs were stored by introducing a QP-specific APIs (starting ~3.5.19). It was discussed in issue #553 , and subsequently PR #564 was merged to allow DeepEP to work with the newer NVSHMEM versions. Can those patches (since moved to legacy in the main branch) also be applied to hybrid-ep? I have a case to use hybrid ep with a newer NVSHMEM version.

I’d be happy to take this.

I think the safest scope is to port the compatibility approach from #564 into hybrid-ep, rather than changing the HybridEP communication design.
