Table 259: Receive List Placement Configuration Register (Offset 0x2010)
Bit Field Description Init Access
31:15 Reserved – 0 RO
14:13 Default Interrupt
Distribution Queue
Default interrupt distribution queue. Number within a class
of service group when the frame has errors, is truncated,
or is a non-IP frame.
00 R/W
12:8 Bad Frames Class Default class for error or truncated frames. These frames
are placed in this class of service group when the Allow
Bad Frame bit (bit 11) is set in the Mode Control Register.
00001 RO
7:3 Number of Active Lists The total number of active receive lists. The value must be
between 1 and 16. This value must be an integer multiple
of the Number of Lists per Distribution Group value.
00000 R/W
2:0 Number of Lists Per
Distribution Group
Specifies the number of lists per interrupt distribution
group. This register must always be a power of 2. For
example, if the system wants four classes of service and
four interrupt distribution lists per class of service, this
value is set to four and the Number of Active Lists value is
set to 16.
000 R/W
