Indeed, I missed them.
These registers are defined from 0 to 8 in the document:
  https://microchip-ung.github.io/lan9662_reginfo/reginfo_LAN9662.html?select=cpu,intr

The code use only the indice 0.
In the next iteration, I will keep indices and update the definition of
registers like that:
  #define LAN966X_OIC_DST_INTR_MAP(_n)   (0x78 + (_n) * 4)

Best regards
Hervé
