15.6.4.2
The receive queue filer receives protocol header properties extracted from the incoming frame by the
eTSEC frame parse engine. A property is defined to be a field extracted from a packet header, such as a
TCP port number or VLAN identifier. As soon as the last identifiable header has been recognized, the filer
commences searching the receive queue filer table, comparing properties in the table against properties
extracted from the frame. This table is illustrated in
property values, stored to the RQPROP field, and indicates how to match and interpret the properties by
setting flags in the RQCTRL field. The eTSEC memory map provides access to these fields by way of an
address register (RQFAR) and two porthole registers (RQFCR and RQFPR).
