[Questions] How to add private attr in ACL KEY Field & ACTION Field in experimental .h

[shanz82]

Hi all, I try to add some private ACL KEY/ACTION field as experimental attrs. Not like other objects, ACL Key fields and Action fields are all in ACL Entry attrs, and has some strict check in meta.(like KEY field range, ACTION field range) I try to add as other experiment attrs, add private KEY Field enum after SAI_ACL_ENTRY_END in my saiaclexperimental.h, meta check can pass, but I'm afraid if it works in SONiC. Are there any examples or suggetions to do this ? Thank you.
