Hi Anatoly,

We have a solution right now that requires a kernel driver to allocate 
large contiguous memory and the DPDK changes in the patch. We would like 
to come to a common upstreamed solution as soon as possible.  So please 
send out the patch as soon as you can and we can test/comment on it.  I 
would hope this is a simple addition and shouldn't take long to come to 
an acceptable implementation.  We need this change for DPDK to operate 
on our devices.

Thanks,
  Scott
