The drivers supplied by ST, although using DMA transfer, are still copying the frame payload to/from pbuf payload using memcpy. If you haven't changed this yourself, you have cache line alignment requirements for the driver's tx/93rd buffers only, but not for pbufs. >TX/RX descriptors are hard coded inside DTCM.

However, I'm almost sure the OP's issue is not solved by simply upgrading.
