Sounds good. E-switch vxlan encapsulation offload is supported from ConnectX4-Lx and onward (CX5, etc) > ConnectX®-4 EN network interface card, 40GbE dual-port QSFP28, PCIe3.0 x8, > tall bracket, ROHS R6 This seems to be CX4 which does not support what you are looking for, just to be sure, send the output of "lspci -nn | grep -i mellanox" > Problem: > ————————— > I can successfully turned on the switchdev mode of my Mellanox NIC.
