Hello Michal,
> I=E2=80=99m running 12-STABLE. Is this a hardware related or possibly a d=
river
bug?
This is probably a driver / module bug.
[1] is a bug on this issue, that I opened some years ago. The last time
I tested the sr-iov functionality it was working if you compile the intel
module with sr-iov support enabled but not with the base module. This
was probably a couple years ago though and on 12-CURRENT before
12 was released.
Personally I suggest you just avoid sr-iov though and use bridges. sr-iov
was
a cool idea but it just failed to get an attraction. Probably several
reasons
for this, based on my experience I would say the primary reason is because
its designed use case is for virtualization, and if you do use this for
virtualization, you trade the ability to do live migrations due to using
physical hardware.
Hope this helps,
Richard Gallamore
