Hi Thomas,

Thanks for reply.

The kernel has older version of PF than the one released on sf.net. So
I'm checking the sf.net release.
If the change is limited in DPDK then it is controllable. But now it
affects Intel's PF driver, I don't even know how to push the feature
to Intel. The driver on sf.net is a read-only repository, isn't it? It
would be painful to maintain another branch of 10G PF driver.
Could Intel give some advice or hints here?

thx &
rgds,
