Return ENOTSUP error code when configuring i40evf promiscuous mode to
fix port start hang issue on platforms which are unsupported to configure
promiscuous mode.
Fixes: ddc7cb0d9453 ("net/i40e: re-program promiscuous mode on VF
interface")

When starting port, rte_eth_dev_start will call rte_eth_dev_config_restore in which promisc configure will be called to enable/disable promiscuous mode. Since "-EAGAIN" was returned if platforms not supported to configure promisc mode, it would return error and stop port starting. /* replay promiscuous configuration */ /* * use callbacks directly since we don't need port_id check and * would like to bypass the same value set */ if (rte_eth_promiscuous_get(port_id) == 1 && *dev->dev_ops->promiscuous_enable != NULL) { ret = eth_err(port_id, (*dev->dev_ops->promiscuous_enable)(dev)); if (ret != 0 && ret != -ENOTSUP) { RTE_ETHDEV_LOG(ERR, "Failed to enable promiscuous mode for device (port %u): %s\n", port_id, rte_strerror(-ret)); return ret; } } else if (rte_eth_promiscuous_get(port_id) == 0 && *dev->dev_ops->promiscuous_disable != NULL) { ret = eth_err(port_id, (*dev->dev_ops->promiscuous_disable)(dev)); if (ret != 0 && ret != -ENOTSUP) { RTE_ETHDEV_LOG(ERR, "Failed to disable promiscuous mode for device (port %u): %s\n", port_id, rte_strerror(-ret)); return ret; } } > > > > > Fixes: ddc7cb0d9453 ("net/i40e: re-program promiscuous mode on VF > > interface") > > Cc: stable@dpdk.org > > > > Signed-off-by: Xiao Zhang <xiao.zhang@intel.com> > > --- > > drivers/net/i40e/i40e_ethdev_vf.c | 8 ++++++++ > > 1 file changed, 8 insertions(+) > > > > diff --git a/drivers/net/i40e/i40e_ethdev_vf.c > > b/drivers/net/i40e/i40e_ethdev_vf.c > > index c34f520..244397e 100644 > > --- a/drivers/net/i40e/i40e_ethdev_vf.c > > +++ b/drivers/net/i40e/i40e_ethdev_vf.c > > @@ -2191,6 +2191,8 @@ i40evf_dev_promiscuous_enable(struct rte_eth_dev > *dev) > > ret = i40evf_config_promisc(dev, 1, vf->promisc_multicast_enabled); > > if (ret == 0) > > vf->promisc_unicast_enabled = TRUE; > > + else if (ret == I40E_NOT_SUPPORTED) > > + ret = -ENOTSUP; > > else > > ret = -EAGAIN; > > > > @@ -2206,6 +2208,8 @@ i40evf_dev_promiscuous_disable(struct > rte_eth_dev *dev) > > ret = i40evf_config_promisc(dev, 0, vf->promisc_multicast_enabled); > > if (ret == 0) > > vf->promisc_unicast_enabled = FALSE; > > + else if (ret == I40E_NOT_SUPPORTED) > > + ret = -ENOTSUP; > > else > > ret = -EAGAIN; > > > > @@ -2221,6 +2225,8 @@ i40evf_dev_allmulticast_enable(struct rte_eth_dev > *dev) > > ret = i40evf_config_promisc(dev, vf->promisc_unicast_enabled, 1); > > if (ret == 0) > > vf->promisc_multicast_enabled = TRUE; > > + else if (ret == I40E_NOT_SUPPORTED) > > + ret = -ENOTSUP; > > else > > ret = -EAGAIN; > > > > @@ -2236,6 +2242,8 @@ i40evf_dev_allmulticast_disable(struct rte_eth_dev > *dev) > > ret = i40evf_config_promisc(dev, vf->promisc_unicast_enabled, 0); > > if (ret == 0) > > vf->promisc_multicast_enabled = FALSE; > > + else if (ret == I40E_NOT_SUPPORTED) > > + ret = -ENOTSUP; > > else > > ret = -EAGAIN; > > > > ^ permalink raw reply [flat|nested] 6+ messages in thread
