Mody, Rasesh Jan. 5, 2017, 7:04 a.m.
This patch includes changes for DCBX like:
 - Return empty parameters for oper-params query when negotiation is not
   complete
 - Use the ieee specific mask value for reading the ethtype value in the
   ieee dcbx mode
 - Endian-ness conversion is not needed for priority<->TC field, as the
   data is already being read/written by ecore in the bigendian way
 - While writing the ets config, base driver incorrectly merges the input
   values with the operational values. The values should be either set
   or unset
 - CEE selection field must be set regardless CEE/IEEE mode
 - Fail the dcbx query for VF interfaces
 - Semantic changes
