Just give the old function a name which makes it's transient purpose
clear rather than this weird foo__() convention.

Something like tc_cls_common_offload_init_compat() or even
tc_cls_common_offload_init_deprecated().

Then people can say "oh, that is serving as a temporary compat
function until everyone is converted, then it is deleted"

Thanks.
