Hey Jason,

         ice(E810 NIC) driver implementation for SIOV virtual device is 
also working in progress. We are working closely with Kevin and Yi on 
the patchset.

         We'll send out the ice patch for SIOV as lan driver user 
example once it is available. (There is some format issue in the last 
email, re-send again and sorry for any inconvenience)

Thanks.
Yahui.
