This section describes the two eTSEC DMA attribute registers.
15.5.3.8.1
The attribute register defines memory access attributes and transaction types used to access buffer
descriptors, to write receive data, and to read transmit data. Snoop enable attributes may be set for reading
buffer descriptors and for reading transmit data.

Attribute Register (ATTR)
Reserved
0 Disables snooping of all receive frames data to memory.
1 Enables snooping of all receive frames data to memory.
0 Disables snooping of all receive BD memory accesses.
1 Enables snooping of all receive BD memory accesses.
Reserved
GADDR0 contains entries 0–31 of the 256-entry group hash table and GADDR7 represents entries
224–255. When RCTRL[GHTX] = 1, GADDR0 contains entries 256–287 of the 512-entry extended group
hash table and GADDR7 represents entries 480–511.
