I am considering purchase of ConnectX-6 VPI card (specifically: MCX653106A-ECAT). It is planned to be used in a small switchless cluster, so I would like to use the Host Chaining feature and connect the cards to each other directly using InfiniBand. The ConnectX-5 firmware known bugs says the Host Chaining requires both ports to be configured to Ethernet (https://docs.mellanox.com/display/ConnectX5Firmwarev16291016/Known+Issues, issue ref: 1178792).
Does this limitation also apply to ConnectX-6 cards ? I have searched through the ConnectX-6 firmware documentation, but nothing is mentioned about the Host Chaining.
Thanks in advance for your help.
