Drv_EddSendCbk with a NULL callback does not work correctly and may result in data abort / non-working Ethernetports

The function Drv_EddSendCbk expects a callback pointer. If this pointer is ommitted the frame cannot be freed correctly internally.

This results in internal management lists to become corrupt and may end in a data abort or out of free frames condition.

Known Workaround:

• Always pass a callback pointer
• Use Drv_EddGetBuffer/Drv_EddSendBuffer
