Add new UAPI to support the mac address from vdpa tool Function vdpa_nl_cmd_dev_config_set_doit() will get the MAC address from the vdpa tool and then set it to the device. The usage is: vdpa dev set name vdpa_name mac **:**:**:**:**:**Why don't you use devlink?Fair question. Why does vdpa-specific uapi even exist? To have driver-specific uapi Does not make any sense to me :/It came with devlink first actually, but switched to a dedicated uAPI. Parav(cced) may explain more here.
Devlink configures function level mac that applies to all protocol devices (vdpa, rdma, netdev) etc. Additionally, vdpa device level mac can be different (an additional one) to apply to only vdpa traffic. Hence dedicated uAPI was added.
