v1.11.2 changes to lan8742.c result in hardfaults #290

Describe the set-up Custom Board STM32CubeIde 1.15.1

Describe the bug I have updated a project from FW 1.11.1 to FW 1.11.2 and now it hardfaults. If I revert the single file Drivers/BSP/Components/lan8742/lan8742.c the hardfault no longer occurs. Also with the v1.11.2 version of the lan8742.c file if I set a breakpoint on line 124 and step through the function and hit continue form line 130 all is good, I suspect this is because of the delay introduced by stepping through the code.

From the 1.11.2 release notes:

BSP Components BSP component lan8742 Remove unnecessary delay.

I think there is an argument that this was the wrong thing to do and the delay is in fact necessary.

Hello @Makin-Things,

We don't have the problem on our side with the ST applications. Could you please provide us with more information about your use case, your ethernet_link_thread function, and in which function you are experiencing the hard fault?
