Bit Name
22 CLE Cluster entry/exit (used in combination with AND bit). This bit brackets clusters, marking the start and end
entries of a cluster. Clusters cannot be nested.
0 Regular RQCTRL entry.
1 If entry matches and AND = 1, treat subsequent entries as belonging to a nested cluster and enter the
cluster; otherwise skip all entries up to and including the next cluster exit. If AND = 0, exit current cluster.
23 REJ Reject frame. This bit and its specified action are ignored if AND = 1.
0 If entry matches, accept frame and file it to RxBD ring Q.
1 If entry matches, reject frame and discard it, ignoring Q.
24 AND Match this entry and the next entry as a pair.
0 Match property[PID] against RQPROP, independent of the next entry.
1 Match property[PID] against RQPROP. If matched and CLE = 0, attempt to match next entry, otherwise,
skip all entries up to and including the entry with AND = 0. If matched and CLE = 1, enter cluster of entries,
otherwise, skip all entries up to and including the entry with CLE = 1 (cluster exit).
25–26 CMP Comparison operation to perform on the RQPROP entry at this index when PID > 0. The property value
extracted by the frame parser is masked by the 32-bit mask_register prior to comparison against RQPROP.
However, the property value is not permanently altered by the value in mask_register . By default,
mask_register is initialized to 0xFFFF_FFFF before each frame is processed.
In the case where PID = 0, CMP is interpreted as follows:
00/01 Filer mask_register is set to all 32 bits of RQPROP, and this entry always matches .
10/11 Filer mask_register is set to all 32 bits of RQPROP, and this entry always fails to match .
In the case where PID > 0, CMP is interpreted as follows (& is bit-wise AND operator):
00 property [PID] & mask_register = RQPROP
01 property [PID] & mask_register >= RQPROP
10 property [PID] & mask_register != RQPROP
11 property [PID] & mask_register < RQPROP
27 — Reserved, should be written with zero.
28–31 PID Property identifier. The value in the RQPROP entry at this index is interpreted according to PID (see
Table 15-34).
15.5.3.3.8 Receive Queue Filer Table Property Register (RQFPR)
RQFPR (see Figure 15-29) is accessed to read or write the RQPROP words in entries of the receive queue
