Sorry that I missed to reply in the previous email. Thanks for the 
details on this topic.

Yes, as "struct oa_tc6" and its members are not or going to be accessed 
in the MAC driver, I will consider this as an opaque structure and 
declare it as void *opaque_oa_tc6 in the MAC driver private structure 
"struct lan865x_priv" and will pass to the APIs exported from oa_tc6.c lib.

Is my understanding correct?
