Hello,

Are Mellanox ASAP² (with ConnectX4 LX / ConnectX 5) or the Netronome counterpart (with Agilio CX) supported to offload Openvswitch with Proxmox ?

Thanks !

Hi,

what offloading do you mean exactly? VLAN offloading, checksum offloading, ......

I mean handling the datapath in the NIC vSwitch, and offloading tc functions (also vlan, vxlan, checksum...).
The less commercial link I could provide is from the RHEL7.5 (https access.redhat com/documentation/en-us/red_hat_enterprise_linux/7/html/7.5_release_notes/new_features_networking#BZ1456687) release note, although I'll put some more since they have schemas, graphs, and command lines.

Mellanox explanations: http www mellanox com/blog/2018/05/mellanox-red-hat-nfv-infrastructure
Mellanox some setup instructions: https community.mellanox com/docs/DOC-2964
README from Mellanox github on eSwitch <-> OVS: https github com/Mellanox/mlxsw/wiki/OVS
Netronome pretty wide explanations of possibilities, I'm interested in case 6: https www netronome com/blog/ovs-offload-models-used-nics-and-smartnics-pros-and-cons

I'm trying things to bypass the no-url limitations for newbies, sorry for the terrible formatting.

We do not support DPDK but I know it is possible to use it as Debian has packages for it which are compatible with the current version of ovs what we use.

Thanks, I'll upgrade the thread if I find the time to setup one of the solution and i would work.
