You can probably fill some of those in 'enum rtl8168_8101_registers'
(DbgReg is already there).

They are a bit old-fashioned.

See rtl8168_8101_registers / DBG_REG / FIX_NAK_{1, 2}.

         ^^ -> missing space.

Add a symbol for the 0xef register ?

Nit: I would rather use an array of array and remove some code duplication.

Otherwise ok.
