However, some PMDs may execute a hardware reset during the port +stop, such as ixgbe. Some kind of reset operations of PMD could clear the +configurations of RSS in the hardware register. This would cause the loss +of RSS configurations that were set during the testpmd initialization. As +a result, I find that I cannot enable RSS and DCB at the same time in the +testpmd command when using Intel 82599 NIC. + +The patch uses rss conf from software instead of reading from the hardware +register when configuring DCB. + +Signed-off-by: Min Zhou <zhoumin(a)loongson.cn> +Acked-by: Stephen Hemminger <stephen(a)networkplumber.org> +Signed-off-by: Donghua Huang <huangdonghua3(a)h-partners.com> +--- + app/test-pmd/testpmd.c | 26 ++++++-------------------- + 1 file changed, 6 insertions(+), 20 deletions(-) + +diff --git a/app/test-pmd/testpmd.c b/app/test-pmd/testpmd.c +index 9e4e99e..e93214d 100644 +--- a/app/test-pmd/testpmd.c ++++ b/app/test-pmd/testpmd.c +@@ -4298,15 +4298,11 @@ const uint16_t vlan_tags[] = { + 24, 25, 26, 27, 28, 29, 30, 31 + }; + +-static int +-get_eth_dcb_conf(portid_t pid, struct rte_eth_conf *eth_conf, +- enum dcb_mode_enable dcb_mode, +- enum rte_eth_nb_tcs num_tcs, +- uint8_t pfc_en) ++static void ++get_eth_dcb_conf(struct rte_eth_conf *eth_conf, enum dcb_mode_enable dcb_mode, ++ enum rte_eth_nb_tcs num_tcs, uint8_t pfc_en) + { + uint8_t i; +- int32_t rc; +- struct rte_eth_rss_conf rss_conf; + + /* + * Builds up the correct configuration for dcb+vt based on the vlan tags array +@@ -4348,12 +4344,6 @@ get_eth_dcb_conf(portid_t pid, struct rte_eth_conf *eth_conf, + struct rte_eth_dcb_tx_conf *tx_conf = + &eth_conf->tx_adv_conf.dcb_tx_conf; + +- memset(&rss_conf, 0, sizeof(struct rte_eth_rss_conf)); +- +- rc = rte_eth_dev_rss_hash_conf_get(pid, &rss_conf); +- if (rc != 0) +- return rc; +- + rx_conf->nb_tcs = num_tcs; + tx_conf->nb_tcs = num_tcs; + +@@ -4365,7 +4355,6 @@ get_eth_dcb_conf(portid_t pid, struct rte_eth_conf *eth_conf, + eth_conf->rxmode.mq_mode = + (enum rte_eth_rx_mq_mode) + (rx_mq_mode & RTE_ETH_MQ_RX_DCB_RSS); +- eth_conf->rx_adv_conf.rss_conf = rss_conf; + eth_conf->txmode.mq_mode = RTE_ETH_MQ_TX_DCB; + } + +@@ -4374,8 +4363,6 @@ get_eth_dcb_conf(portid_t pid, struct rte_eth_conf *eth_conf, + RTE_ETH_DCB_PG_SUPPORT | RTE_ETH_DCB_PFC_SUPPORT; + else + eth_conf->dcb_capability_en = RTE_ETH_DCB_PG_SUPPORT; +- +- return 0; + } + + int +@@ -4398,10 +4385,9 @@ init_port_dcb_config(portid_t pid, + /* retain the original device configuration. */ + memcpy(&port_conf, &rte_port->dev_conf, sizeof(struct rte_eth_conf)); + +- /*set configuration of DCB in vt mode and DCB in non-vt mode*/ +- retval = get_eth_dcb_conf(pid, &port_conf, dcb_mode, num_tcs, pfc_en); +- if (retval < 0) +- return retval; ++ /* set configuration of DCB in vt mode and DCB in non-vt mode */ ++ get_eth_dcb_conf(&port_conf, dcb_mode, num_tcs, pfc_en); ++ + port_conf.rxmode.offloads |= RTE_ETH_RX_OFFLOAD_VLAN_FILTER; + /* remove RSS HASH offload for DCB in vt mode */ + if (port_conf.rxmode.mq_mode == RTE_ETH_MQ_RX_VMDQ_DCB) { +-- +2.33.0 + diff --git a/0128-app-testpmd-add-prio-tc-map-in-DCB-command.patch b/0128-app-testpmd-add-prio-tc-map-in-DCB-command.patch new file mode 100644 index 0000000..ad4ea47 --- /dev/null +++ b/0128-app-testpmd-add-prio-tc-map-in-DCB-command.patch @@ -0,0 +1,296 @@ +From ebb9eb84c710366d9a42a95e2e4168eb3b2b027a Mon Sep 17 00:00:00 2001 +From: Chengwen Feng <fengchengwen(a)huawei.com> +Date: Thu, 24 Apr 2025 14:17:47 +0800 +Subject: [PATCH 15/24] app/testpmd: add prio-tc map in DCB command + +[ upstream commit 601576ae6699b31460f35816be54a63c34f54377 ] + +Currently, the "port config 0 dcb ..." command config the prio-tc map +by remainder operation, which means the prio-tc = prio % nb_tcs. + +This commit introduces an optional parameter "prio-tc" which is the same +as kernel dcb ets tool.
