When using a VDPA device, it is important to ensure that the MAC address is correctly set. In this patch series, we add a new parameter to enable this check. Only three MAC setup configurations are acceptable; any other will fail to boot.
The usage is: .... -netdev type=vhost-vdpa,vhostdev=/dev/vhost-vdpa-0,id=vhost-vdpa0,check-mac=true\ -device virtio-net-pci,netdev=vhost-vdpa0\ .... tested by ConnectX-6 Dx/vdpa_sim device change in v3 1. add a new parameter to enable the check and keep the old behavior 2. adjust the comment and make it more clear change in v4 1. change the new parameter's name to check-mac 2. change the comment and make it more clear change in v5 1.These patches haven't been merged for a while, so I rebased them with the latest code and resubmitted change in v6 1. Address comments 2. Rebase with the latest QEMU Cindy Lu (4): vhost_vdpa : Add a new parameter to enable check mac address virtio_net: Add the check for vdpa's mac address virtio_net: Add second acceptable configuration for MAC setup virtio_net: Add third acceptable configuration for MAC setup. hw/net/virtio-net.c | 66 ++++++++++++++++++++++++++++++++++++++++++++- include/net/net.h | 1 + net/vhost-vdpa.c | 4 +++ qapi/net.json | 5 ++++ 4 files changed, 75 insertions(+), 1 deletion(-) -- 2.45.0
