ETH_UpdateDescriptor() uses ETH_RX_BUF_SIZE define instead of user supplied value

[Maashau]

ETH_InitTypeDef has user supplied member RxBuffLen. In ETH_UpdateDescriptor() ETH_RX_BUF_SIZE is used instead:

STM32CubeF7/Drivers/STM32F7xx_HAL_Driver/Src/stm32f7xx_hal_eth.c

Line 1234 in 6a3b9bb

WRITE_REG(dmarxdesc->DESC1, ETH_DMARXDESC_DIC | ETH_RX_BUF_SIZE | ETH_DMARXDESC_RCH);

STM32CubeF7/Drivers/STM32F7xx_HAL_Driver/Src/stm32f7xx_hal_eth.c

Line 1238 in 6a3b9bb

WRITE_REG(dmarxdesc->DESC1, ETH_RX_BUF_SIZE | ETH_DMARXDESC_RCH);

Also in ETH_DMARxDescListInit():

STM32CubeF7/Drivers/STM32F7xx_HAL_Driver/Src/stm32f7xx_hal_eth.c

Line 3000 in 6a3b9bb

dmarxdesc->DESC1 = ETH_DMARXDESC_RCH | ETH_RX_BUF_SIZE;

This makes RxBuffLen cause confusion and makes it pretty useless as it has to be the same value as the define.
