From: Kalesh AP Date: Thu, 6 Feb 2020 16:33:08 +0000 (+0530) Subject: net/bnxt: fix unnecessary delay in port stop X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=967a722be08cacdd05e6a29d2e1790d5747a6217;p=dpdk.git net/bnxt: fix unnecessary delay in port stop VFs and multifunction PFs do not have the privilege to change link configuration. We force the physical link down as a part of device stop only for single physical function(SPF). This change also helps in eliminating the logs when a VF port is stopped: "Port 0: link state change event" "bnxt_print_link_info(): Port 0 Link Up - speed 25000 Mbps - full-duplex" Fixes: 316e412299fd ("net/bnxt: fix crash when closing") Cc: stable@dpdk.org Signed-off-by: Kalesh AP Reviewed-by: Somnath Kotur Reviewed-by: Ajit Khaparde --- diff --git a/drivers/net/bnxt/bnxt_ethdev.c b/drivers/net/bnxt/bnxt_ethdev.c index c1cb40160b..537820960e 100644 --- a/drivers/net/bnxt/bnxt_ethdev.c +++ b/drivers/net/bnxt/bnxt_ethdev.c @@ -948,9 +948,10 @@ static void bnxt_dev_stop_op(struct rte_eth_dev *eth_dev) bnxt_dev_set_link_down_op(eth_dev); /* Wait for link to be reset and the async notification to process. - * During reset recovery, there is no need to wait + * During reset recovery, there is no need to wait and + * VF/NPAR functions do not have privilege to change PHY config. */ - if (!is_bnxt_in_error(bp)) + if (!is_bnxt_in_error(bp) && BNXT_SINGLE_PF(bp)) bnxt_link_update(eth_dev, 1, ETH_LINK_DOWN); /* Clean queue intr-vector mapping */
