Hello DPDK users, I met an issue while testing dpdk bond mode 4: the net_bonding vdev cannot work while the slave devices boot sequence is not same as EAL parameters configuration. I create my bonding vdev by EAL parameters: "--file-prefix rte --log-level pmd.net.bond:debug --vdev net_bonding0,mode=4,slave=0000:01:00.0,slave=0000:02:00.0" Thus we have: port0 = "0000:01:00.0" port1 = "0000:02:00.0" Success senario: 1. port0 ready then port 1 ready; " bond_mode_8023ad_register_lacp_mac(951) - forced allmulti for port 0 bond_mode_8023ad_register_lacp_mac(951) - forced allmulti for port 1 mux_machine(532) - Bond 4: slave id 0 distributing started. mux_machine(532) - Bond 4: slave id 1 distributing started. " 1. After bonding successfully, port1 down and up, it could be in bond state again Fail senario: 1. port 1 ready then port 0 ready (all in suspend state) " bond_mode_8023ad_register_lacp_mac(951) - forced allmulti for port 1 bond_mode_8023ad_register_lacp_mac(951) - forced allmulti for port 0 /* then no distributing started prints */ " 1. After bonding successfully, port 0 down and up( then port 0 will stay in suspend state) ENV: DPDK: v19.11.6 Switch config: lacp passive mode, same priority for the connected two ports Does any one met the same issue ? Is this a dpdk bond bug ? Hope to receive your response. Thanks in advance. Br, Christian
