I am trying to understand how all the different attributes like NFTA_CT_KEY are processed in the kernel. Other than guessing how the kernel source actually reads and parses and processes the attributes, is there a reference available that gives the human understanding behind the kernel source. I have different ops like "ct", "cmp", and "bitwise" (and others), but want to understand the "registers" and ops. Any suggestions appreciated.
