From: Ioana Ciornei <[email protected]>
DPAA2 will not support MC firmware versions prior to MC v10.x.
Update the MC interface code and drivers to reflect this.
-update the object .h files and code that builds commands to include
the new command version in the command header
-object versions are no longer available in the object attributes,
so remove references to them and instead get the version from the
new get_api_version() command
-create/destroy commands for all objects have new arguments
-dpmng_get_container_id() is replaced by dprc_get_container_id()
All MC firmware versions >= 10 will be supported going forward.
