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...
