Hi Jakob, I'm unsure what the considerations were when setting this limit, but I do note that it was increased once before, from 5 to 6, for an OVN use-case [1]. So this approach seems reasonable to me. Acked-by: Simon Horman <[email protected]> [1] dpif-netdev: Set MAX_RECIRC_DEPTH to 6. https://github.com/openvswitch/ovs/commit/3f9d3836d63a _______________________________________________ dev mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-dev
