Funny, I recently ran the TCP test suite on my STM32H743 board and it was able to pass just fine. STM32F7, though, appears to currently have broken networking. This was on my mbed-ce fork though so not sure if anything's different there...

As an extra data point, this did also work just fine on a STM32H743 for me.
The issue appears to be (mostly) with the MPU config on the STM32H745(and any other of the dual core H7 family), where after making some local modifications to \connectivity\drivers\emac\TARGET_STM\stm32xx_emac.cpp for the mpu config to match what it is in some of the H745 examples from stm_cube
