Hi mlnx teams,
How can I enable VF LAG with switch mode in the upstrem dpdk? echo 1 > /sys/class/net/net2/device/sriov_numvfs echo 1 > /sys/class/net/net3/device/sriov_numvfs echo 0000:19:00.2 > /sys/bus/pci/drivers/mlx5_core/unbind echo 0000:19:08.1 > /sys/bus/pci/drivers/mlx5_core/unbind devlink dev eswitch set pci/0000:19:00.0 mode switchdev encap enable devlink dev eswitch set pci/0000:19:00.1 mode switchdev encap enable sleep 2 ip l add dev bond0 type bond mode 802.3ad ifconfig bond0 172.168.153.50/24 up echo 1 > /sys/class/net/bond0/bonding/xmit_hash_policy ifconfig net2 down ip l set dev net2 master bond0 ifconfig net3 down ip l set dev net3 master bond0 ifconfig net2 up ifconfig net3 up I create one VF on each PF and unbind the VF. Then enable the eswitch mode for each PF. Then bond the PFs to a lacp linux bond. I can see the lag success. mlx5_core 0000:19:00.0: modify lag map port 1:1 port 2:1 mlx5_core 0000:19:00.0: modify lag map port 1:1 port 2:2 But I check the dpdk codes in mlx5_device_bond_pci_match, The VF lag mode depends on the IB device with bond name. But in the eswitch mode, There will be no mlx_bond_0 IB device. The bond IB device will come out only in legacy mode. ls /sys/class/infiniband/ mlx5_0 mlx5_1 So Is there some way to enable VF LAG with switchdev mode in dpdk for mlx5?
