    "content": "In the devargs syntax for device representors, it is possible to add\nseveral devices at once: -w dbdf,representor=[0-3]\nIt will become a more frequent case when introducing wildcards\nand ranges in the new devargs syntax.\n\nIf a devargs string is provided for probing, and updated with a bigger\nrange for a new probing, then we do not want it to fail because\npart of this range was already probed previously.\nThere can be new ports to create from an existing rte_device.\n\nThat's why the checks for an already probed device\nare moved as PMD responsibility.\nOnly the PMD knows the ports attached to one rte_device.\n\nIn the case of vdev, a global check is kept in insert_vdev(),\nassuming that a vdev will always have only one port.\nIn the case of NXP buses, the probing is done only once (no hotplug),\nthough a check is added at bus level for consistency.\n\nAs another consequence of being able to probe in several steps,\nthe field rte_device.devargs must not be considered as a full\nrepresentation of the rte_device, but only the latest probing args.\nAnyway, the field rte_device.devargs is used only for probing.\n\nSigned-off-by: Thomas Monjalon <thomas@monjalon.net>\n---\n drivers/bus/dpaa/dpaa_bus.c                |  3 +++\n drivers/bus/fslmc/fslmc_bus.c              |  3 +++\n drivers/bus/ifpga/ifpga_bus.c              | 13 ++++++-----\n drivers/bus/pci/pci_common.c               | 15 +++++++------\n drivers/bus/vdev/vdev.c                    |  5 +++++\n drivers/bus/vmbus/vmbus_common.c           | 25 +++++++++++-----------\n drivers/common/qat/Makefile                |  3 ++-\n drivers/common/qat/meson.build             |  1 +\n drivers/common/qat/qat_device.c            |  3 +++\n drivers/compress/octeontx/otx_zip_pmd.c    |  3 +++\n drivers/crypto/virtio/Makefile             |  1 +\n drivers/crypto/virtio/meson.build          |  1 +\n drivers/crypto/virtio/virtio_cryptodev.c   |  3 +++\n drivers/event/octeontx/ssovf_probe.c       |  6 ++++++\n drivers/event/skeleton/Makefile            |  1 +\n drivers/event/skeleton/meson.build         |  1 +\n drivers/mempool/octeontx/Makefile          |  1 +\n drivers/mempool/octeontx/meson.build       |  2 ++\n drivers/mempool/octeontx/octeontx_fpavf.c  |  3 +++\n drivers/net/ark/Makefile                   |  1 +\n drivers/net/ark/meson.build                |  1 +\n drivers/net/avf/Makefile                   |  1 +\n drivers/net/avp/Makefile                   |  1 +\n drivers/net/avp/meson.build                |  1 +\n drivers/net/axgbe/Makefile                 |  1 +\n drivers/net/axgbe/meson.build              |  2 ++\n drivers/net/bnx2x/Makefile                 |  1 +\n drivers/net/bnx2x/meson.build              |  1 +\n drivers/net/bnxt/Makefile                  |  1 +\n drivers/net/bnxt/meson.build               |  1 +\n drivers/net/cxgbe/Makefile                 |  1 +\n drivers/net/cxgbe/meson.build              |  2 ++\n drivers/net/e1000/Makefile                 |  1 +\n drivers/net/e1000/meson.build              |  2 ++\n drivers/net/enic/Makefile                  |  1 +\n drivers/net/enic/meson.build               |  2 ++\n drivers/net/fm10k/Makefile                 |  1 +\n drivers/net/fm10k/meson.build              |  2 ++\n drivers/net/i40e/i40e_ethdev.c             |  3 +++\n drivers/net/ifc/ifcvf_vdpa.c               |  3 +++\n drivers/net/ixgbe/ixgbe_ethdev.c           |  3 +++\n drivers/net/liquidio/Makefile              |  1 +\n drivers/net/liquidio/meson.build           |  1 +\n drivers/net/mlx4/mlx4.c                    |  4 ++++\n drivers/net/mlx5/mlx5.c                    |  4 ++++\n drivers/net/netvsc/hn_ethdev.c             |  9 +++++---\n drivers/net/nfp/Makefile                   |  1 +\n drivers/net/nfp/meson.build                |  1 +\n drivers/net/nfp/nfp_net.c                  |  3 +++\n drivers/net/octeontx/Makefile              |  3 +--\n drivers/net/octeontx/base/meson.build      |  2 +-\n drivers/net/octeontx/base/octeontx_pkivf.c |  3 +++\n drivers/net/octeontx/base/octeontx_pkovf.c |  3 +++\n drivers/net/qede/Makefile                  |  1 +\n drivers/net/qede/meson.build               |  2 ++\n drivers/net/szedata2/Makefile              |  1 +\n drivers/net/szedata2/meson.build           |  1 +\n drivers/net/szedata2/rte_eth_szedata2.c    |  3 +++\n drivers/net/thunderx/Makefile              |  1 +\n drivers/net/thunderx/meson.build           |  2 ++\n drivers/raw/ifpga_rawdev/ifpga_rawdev.c    |  3 +++\n lib/librte_eal/common/eal_common_dev.c     |  5 -----\n lib/librte_eal/common/include/rte_dev.h    |  2 +-\n lib/librte_ethdev/rte_ethdev_pci.h         |  3 +++\n lib/librte_eventdev/rte_eventdev_pmd_pci.h |  3 +++\n 65 files changed, 152 insertions(+), 36 deletions(-)",
