I've had a quick look at the ethernetif.c file generated by CubeMX: at least for the F439, it returns ERR_USE when no more TX DMA descriptors are available. This is clearly a bug as ERR_USE means "Address in use" (and it has been like that since the beginning of the universe). ERR_MEM would be a better return value. [You might want to report that bug back to STM] In any case, you try to send faster than the chip or the cable can...
