[PATCH v3 0/4] virtio_net: Add the check for vdpa's mac address

Posted by Cindy Lu 1 year, 3 months ago

When using a VDPA device, it is important to ensure that the MAC
address is correctly set.Here we add Add a new parameter to 
enable this check.
There are only three acceptable situations for MAC setup; any other
configuration will fail to boot.

The usage is:
....
-netdev type=vhost-vdpa,vhostdev=/dev/vhost-vdpa-0,id=vhost-vdpa0,macstrickcheck=true\
-device virtio-net-pci,netdev=vhost-vdpa0\
....

tested by ConnectX-6 Dx 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
