It may be\nextended in next revision to support other configs like\nlink state.\n\nRegarding the MAC selection strategy, if devargs MAC address\nis set by the user and valid, the driver tries to store it\nin the device config space, then it reads the MAC address\nback from the device config, which will be used. If not set\nin devargs or invalid, it tries to read it from the device.\nIf it fails, a random MAC will be used.\n\nI'm interrested to know your feedback on this strategy.\n\nIt has been tested with vDPA simulator, which only supports\ngetting the MAC address, and witch CX6 which supports neither\ngetting or setting MAC address (and so devarg or random MAC is\nused). IFCVF driver seems to support both getting and setting\nthe MAC, I have a try with it before next revision.\n\nMaxime Coquelin (3):\n net/virtio: keep device and frontend features separated\n net/virtio: add device config support to vDPA\n net/virtio: add MAC device config getter and setter\n\n drivers/net/virtio/virtio_user/vhost.h | 3 +\n drivers/net/virtio/virtio_user/vhost_vdpa.c | 69 +++++++++++++++\n .../net/virtio/virtio_user/virtio_user_dev.c | 88 +++++++++++++++----\n .../net/virtio/virtio_user/virtio_user_dev.h | 2 +\n drivers/net/virtio/virtio_user_ethdev.c | 12 ++-\n 5 files changed, 151 insertions(+), 23 deletions(-)", "diff": null, "prefixes": [ "RFC", "0/3" ] }
