PKT_RX_MAC_ERR was set in the mbuf->ol_flags if packet_error was set and used later to indicate an error packet. But since PKT_RX_MAC_ERR is defined as 0, mbuf flags and packet types and length were being misinterpreted. - + Make the function enic_cq_rx_to_pkt_err_flags() return true for error packets and use the return value instead of mbuf->ol_flags to indicate error packets. Also remove warning for error packets and rely on rx_error stats. - + Fixes: 947d860c821f ("enic: improve Rx performance") - + Signed-off-by: John Daley <johndale@cisco.com> +--- + drivers/net/enic/enic_rx.c | 43 ++++++++++++++++++------------------------- + 1 file changed, 18 insertions(+), 25 deletions(-) diff --git a/drivers/net/enic/enic_rx.c b/drivers/net/enic/enic_rx.c index 59ebaa4..817a891 100644 @@ -110,3 +112,6 @@ index 59ebaa4..817a891 100644 /* prefetch mbuf data for caller */ rte_packet_prefetch(RTE_PTR_ADD(rxmb->buf_addr, +-- +1.9.1 + |
