ERROR_NDIS_INVALID_PORT_STATE
ERROR_NDIS_INVALID_PORT_STATE The port exists, but its current state does not permit the requested action. A port can be initializing, paused, inactive, closing, or otherwise unavailable for a particular operation.
What to check
- Query the port state before applying a configuration change or sending data.
- Wait for a documented lifecycle transition instead of forcing an operation during setup or teardown.
- Check for a preceding adapter reset, media loss, or role change that altered port state.
