H A D | nic_common.h | a81dcd85 Thu Jul 02 11:29:58 CDT 2020 Edward Cree <ecree@solarflare.com> sfc: assign TXQs without gaps
Since we only allocate VIs for the number of TXQs we actually need, we cannot naively use "channel * TXQ_TYPES + txq" for the TXQ number, as this has gaps (when efx->tx_queues_per_channel < EFX_TXQ_TYPES) and thus overruns the driver's VI allocations, causing the firmware to reject the MC_CMD_INIT_TXQ based on INSTANCE. Thus, we distinguish INSTANCE (stored in tx_queue->queue) from LABEL (tx_queue->label); the former is allocated starting from 0 in efx_set_channels(), while the latter is simply the txq type (index in channel->tx_queue array). To simplify things, rather than changing tx_queues_per_channel after setting up TXQs, make Siena always probe its HIGHPRI queues at start of day, rather than deferring it until tc mqprio enables them.
