Needs to conform to the way ChibiOS configures things

So I think what you need to do is add a config item to hal_mmc_lld.h, something like:
/**
* @brief <docs in here>
*/
#if !defined(STM32_MAC_PHY_FIXED_LINK) || defined(__DOXYGEN__)
#define STM32_MAC_PHY_FIXED_LINK FALSE
#endif
/**
* @brief <docs in here>
*/
#if !defined(STM32_MAC_PHY_FIXED_LINK_TYPE) || defined(__DOXYGEN__)
#define STM32_MAC_PHY_FIXED_LINK_TYPE LINK_100_FULLDUPLEX
#endif
and then adjust the source appropriately for these

Thanks - I will ping the ChibiOS guys

@vrsanskytom Can you give an example of the connectivity here? Which switch are you testing this on? |
Sure, please take a look at following diagram, describing our board architecture. Onboard FMU is the device running on STM which is a subject of this issue. https://docs.airvolute.com/dronecore-autopilot/dcs2/.pilot-boards/dcs2.pilot-v-1.0/peripherals We are using ethernet switch from microchip KSZ family, but this will be common issue for all switches not mastered by STM. |

The goal of this PR is to support the case when STM32 MCU is connected through MII/RMII with fixed link parameters. For example, in more complex systems where FMU is connected directly to ethernet switch, which is not mastered by STM through MDIO bus. In this case, the link parameters are defined in board definition file.
