eth_stm32: write PHY registers for fixed link #10

Copy link

Various tweaks to the STM32 Ethernet driver to make it work more reliably in our use case:

  • Support resetting the PHY (via reset GPIO or soft reset)
  • Initialize PHY configuration for fixed link speeds
    • This is based on the existing Kconfig settings, rather than any configuration in the device tree.
  • Allow configuring Auto MDI-X

eth_stm32: write PHY registers for fixed link
21edeb8 
- If Kconfig for the STM32 Ethernet driver specifies a fixed link speed,
  write this to the PHY control registers when the driver is being
  initialized

- Allow disabling auto-MDIX and force a specific channel order
