Description
Number of packets received that are 1024-maximum bytes in length.
This register counts the number of good packets received that are from 1024 bytes to
the maximum (from <Destination Address> through <CRC>, inclusively) in length. The
maximum is dependent on the current receiver configuration and the type of packet
being received. If a packet is counted in the Receive Oversized Count register, it is not
counted in this register (see Section 9.2.7.36). This register does not include received
flow control packets and only increments if the packet has passed address filtering and
receives are enabled.
Due to changes in the standard for maximum frame size for VLAN tagged frames in
802.3, this device accepts packets which have a maximum length of 1522 bytes. The
RMON statistics associated with this range has been extended to count 1522 byte long
packets.

Initial
Value
0x0
Description
Number of good packets received (of any length).
This register counts the number of good (non-erred) packets received of any legal
length. The legal length for the received packet is defined by the value of LPE (see
Section 9.2.7.13). This register does not include received flow control packets and only
counts packets that pass filtering. This register only increments if receives are enabled.
This register does not count packets counted by the Missed Packet Count (MPC)
register.
Broadcast Packets Received Count - BPRC (0x04078; R)
Field
BPRC
Bit(s)
31:0
Initial
Value
0x0
Description
Number of broadcast packets received.
This register counts the number of good (non-erred) broadcast packets received. This
register does not count broadcast packets received when the broadcast address filter is
disabled. This register only increments if receives are enabled.
