Code Review
This PR introduces an allow_mnnvl flag to the DeepEP Buffer initialization, defaulting to True. This change is linked to an external DeepEP pull request and aims to fix errors in certain environments. The primary feedback focuses on the hardcoded True value for allow_mnnvl. While this may serve as an immediate fix, the associated TODO comment suggests it's not always the optimal setting. To enhance robustness and adaptability, it's recommended to explore making this flag configurable (e.g., through server arguments or environment variables) or dynamically determined based on runtime conditions. This would provide users more control and potentially better performance in environments where MNNVL is not required or could be problematic.

The TODO comment is a good indicator that allow_mnnvl=True might be a default that isn't universally optimal. While True might fix the errors in "some environments" as the PR title suggests, making this behavior configurable could offer better adaptability and performance across diverse setups.
Consider introducing a mechanism to set allow_mnnvl based on runtime conditions or configuration. For instance, this could be a new field in ServerArgs or an environment variable.
This would allow overriding the default if MNNVL is known to be unneeded or problematic in a specific environment, without requiring further code changes. If the conditions for setting it to False are programmatically detectable (e.g., hardware check), that would be even better.
| # TODO can be false when unneeded | |
| allow_mnnvl=True, | |
| # TODO: Determine if allow_mnnvl can be dynamically set to false when unneeded, e.g., via ServerArgs or env var. | |
| allow_mnnvl=global_server_args_dict.get("deepep_allow_mnnvl", True), |
