Up until now this driver only worked with data cache disabled. To make it work with enabled data cache following changes were required:

• Flush Tx/Rx buffer descriptors their modification
• Invalidate Tx/Rx buffer descriptors before reading its values
• Flush cache for data passed from CPU to GMAC
• Invalidate cache for data passed from GMAC to CPU
