Hi,
While browsing through the ixgbe pmd code, I noticed that there is
ixgbe_recv_pkts_bulk_alloc, which can be enabled if the following preconditions
are met.
* rxq->rx_free_thresh >= RTE_PMD_IXGBE_RX_MAX_BURST
* rxq->rx_free_thresh < rxq->nb_rx_desc
* (rxq->nb_rx_desc % rxq->rx_free_thresh) == 0
* rxq->nb_rx_desc<(IXGBE_MAX_RING_DESC-RTE_PMD_IXGBE_RX_MAX_BURST)
I presume the difference from the normal (non bulk) version has to do with
buffer allocation. Can someone please explain the inner working of bulk_alloc
and why one may or may not want to enable bulk_alloc mode?
I only see bulk_alloc is available for ixgbe driver and not igb and e1000. Why
is that?
Thanks.
Dan
