Add the function to support setting the MAC address.
For vdpa_sim_net, the driver will write the MAC address
to the config space, and other devices can implement
their own functions to support this.

e there is a request to use kthread.
In this PATCH, the support of kthread is added back. Additionally,
a module_param is added to enforce which mode we are using, and
a new UAPI is introduced to allow the userspace app to set the
mode they want to use.
Tested the userspace application with QEMU.
C
Add a new module parameter to enable kthread while loading modules.
This parameter will identify if the vhost will use kthread or a task.
The default value will be true.
