[v4,0/4] virtio_net: Add the check for vdpa's mac address

Message

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 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
