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
