DMA Descriptor Structure
The structure is common for both receive and transmit descriptors
The descriptor is of 4 words, but our structrue contains 6 words where
last two words are to hold the virtual address of the network buffer pointers
for driver's use
From the GMAC core release 3.50a onwards, the Enhanced Descriptor structure got changed.
The descriptor (both transmit and receive) are of 8 words each rather the 4 words of normal
descriptor structure.
Whenever IEEE 1588 Timestamping is enabled TX/RX DESC6 provides the lower 32 bits of Timestamp value and
TX/RX DESC7 provides the upper 32 bits of Timestamp value
In addition to this whenever extended status bit is set (RX DESC0 bit 0), RX DESC4 contains the extended status information
