Contribution description

When we put the interface to sleep, also disable the PHY. This saves 75 µA of current on the same54-xpro (value will differ depending on the PHY used)

  • idle 13.88 mA
  • MAC off 11.48 mA
  • MAC+PHY off 10.73 mA

Testing procedure

🕐 Waiting for PR status (GitHub check) to be set, probably by CI. Bors will automatically try to run when all required PR statuses are set.
