- PHY default configuration can be changed
- AutoNegotiation
- Speed
- DuplexMode
- PHY register offset can be updated depending on chosen PHY
All unused parameters are cleaned.
DISCO_F769NI EMAC driver may return ethernet packet with illegal
length when driver is under heavy load. In one case, the received
bytes indicate frame length of 53 bytes but advertised data length
was 65518 bytes. In another case EMAC driver variable
`EthHandle.RxFrameInfos.length` contained value 0xFFFF FFFC.
As a work-around accept only 1-1500 bytes long ethernet packets.
ARCH_MAX board uses 0x01 as PHY address, different from other NUCLEO STM32 boards. To faciliate change of PHY address of customized boards, a configuration entry eth-phyaddr was added and can be overriden as needed in mbed_app.json by adding "stm32-emac.eth-phyaddr": X. Macro ETH_ARCH_PHY_ADDRESS was also renamed to ETH_PHY_ADDRESS, because it is not only used by ARCH_MAX board but also other boards.
