Intel^® 82598EB 10 GbE Controller - Register Descriptions
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, the 82598
accepts packets that have a maximum length of 1522 bytes. RMON statistics associated with this range
has been extended to count 1522 byte long packets.
4.4.3.9.23 Good Packets Received Count – GPRC (0x04074; R)
Field
GPRC
Bit(s)
Initial
Value
Description
31:0
0x0
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 LongPacketEnable (see Section 4.4.3.9.8). The
register does not include received flow control packets and only counts packets that pass filtering. It
only increments if receives are enabled and does not tally packets counted by the Missed Packet Count
(MPC) register.
GPRC might count packets interrupted by link disconnect although they have a CRC error
4.4.3.9.24 Broadcast Packets Received Count – BPRC (0x04078; R)
Field
BPRC
Bit(s)
Initial
Value
Description
31:0
0x0
Number of broadcast packets received.
This register counts the number of good (non-erred) broadcast packets received. It does not count
broadcast packets received when the broadcast address filter is disabled and only increments if receives
are enabled.
4.4.3.9.25 Multicast Packets Received Count – MPRC (0x0407C; R)
Field
MPRC
Bit(s)
Initial
Value
Description
31:0
0x0
Number of multicast packets received.
This register counts the number of good (non-erred) multicast packets received. It does not tally
multicast packets received that fail to pass address filtering or received flow control packets. This
register only increments if receives are enabled and does not tally packets counted by the Missed
Packet Count (MPC) register.
