This code looks very generic and not tailored to linux.
Are you intending to fix it to be more linux-kernel like?

Dear John and Don,
Thanks for kind reply.
This ARM SoC doesnt have additional features for virtualization like VT-d.
And I'm not going to use SR-IOV for virtualization. I just want to do some
experimental VF test only with limited 2 or 4.
BTW, I have one more question about this.
Do you mean roo
Add lls socket option support.
use --lls (value in usecs) to override global setting.
Right now we always get and print the value of the option before we set,
to show that the option works properly.
This should be removed in an official release.

Hello,
No it's not possible. MSI-X is needed so that interrupts can be routed to each
guest. With MSI there is only a single interrupt so there is no way to route
it to multiple VF's. MSI-X is a requirement for SR-IOV support. So don's

Hey Minho,
I believe that it would be problematic at best since as MSI uses identical
address for all vectors in a Function and differentiates vectors in a Function
only by LSBs in data.
