Following various issues seen in deployments that involved mlx5 devices, here is a proposal to disable DPDK initial device probing.
Changing this as the default behavior should be fine as OVS relies on hotplugs for many years now. But in case something gets broken, keep an option to restore the original behavior. As for what to expect on DPDK side in the future, the new option has been merged in preparation of v26.07-rc1. See: https://git.dpdk.org/dpdk/commit/?id=7baf81674a01 -- David Marchand Changes since v1: - improved documentation wording and references, - avoided allocating memory for error strings in patch 1, - added checks for --allow/--block and --no-pci options in patch 2, Changes since RFC v2: - updated descriptions and comments as Eelco suggested, Changes since RFC v1: - adjusted logs in patch 1, - handled other DPDK buses in patch 2, David Marchand (2): netdev-dpdk: Enhance logging for port hotplug. dpdk: Disable initial device probe.
