From: Hemant Agrawal <[email protected]> The driver has no way to hold an Rx queue down while the port is started, and dpaa2_rxq_info_get() already reports rx_deferred_start as 0. The Tx side rejects the request; do the same for Rx instead of silently accepting a configuration that will not be honoured.
