From: Marek Kasiewicz <[email protected]> Remove the advertisement of RTE_ETH_DEV_CAPA_RUNTIME_RX_QUEUE_SETUP and RTE_ETH_DEV_CAPA_RUNTIME_TX_QUEUE_SETUP capabilities from the iavf VF driver.
Runtime queue setup on E810 VFs causes queue state corruption when queues are dynamically reconfigured while the hardware rate limiter is actively pacing TX queues. Queue configuration messages to the PF via virtchnl can race with ongoing TX operations, leading to undefined behavior. By not advertising these capabilities, all queues are configured at port start and remain stable throughout the port lifecycle.
