RQFAR, shown in
received queue filer table. Each table entry occupies a pair of 32-bit words, denoted RQCTRL and
RQPROP. To access the RQCTRL and RQPROP words of entry n, write n to RQFAR. Then read or write
the indexed RQCTRL and RQPROP words by reading or writing the RQFCR and RQFPR registers,
respectively.

14.5.3.3.7
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.
