15.5.3.3.7 Receive Queue Filer Table Control Register (RQFCR)
RQFCR is accessed to read or write the RQCTRL words in entries of the receive queue filer table. The
table entries are described in greater detail in
through RQFCR is defined by the current value of RQFAR.
Figure 15-28 describes the definition for the RQFCR register.

Table 15-33 describes the fields of the RQFCR register.
Bit Name
0 GPI General purpose interrupt. When a property matches the value in the RQPROP entry at this index, and
REJ = 0 and AND = 0, the filer will instruct the Rx descriptor controller to set IEVENT[FGPI] when the
corresponding receive frame is written to memory.
If the timer is enabled (TMR_CTRL[TE] = 1), then TMR_PEVENT[RXP] will also be set.
1–15 — Reserved, should be written with zero.
16–21 Q Receive queue index, from 0 to 63, inclusive, written into the Rx frame control block associated with the
received frame. When a property matches the value in the RQPROP entry at this index, and REJ = 0 and
AND = 0, the frame is sent to either RxBD ring 0 (if RCTRL[FSQEN] = 1) or the RxBD ring with index (Q mod
8) and the filing table search is terminated. In the case where RCTRL[FSQEN] = 0, 8 virtual receive queues
are overlaid on every RxBD ring, and software needs to consult the RQ field of the Rx frame control block to
determine which virtual receive queue was chosen.
