Bit
Description
26
UDPE UDP Checksum Error
When set, indicates that the received frame is an UDP/IP packet and its UDP checksum field
does not match.
This bit is valid only when last descriptor is set.
25
ES Error Summary
Indicates the logical OR of the following RDES0 bits:
CRC error
Frame too long
Runt frame
This bit is valid only when last descriptor is set.
24
MF Multicast Frame
When set, indicates that this frame has a multicast address.
This bit is valid only when last descriptor is set.
23 - 20
SPN Switch Engine Source Port Number
This field indicates the source port where the packet originated.
If bit 20 is set, it indicates the packet was received from port 1. If bit 21 is set, it indicates the
packet was received from port 2.
This field is valid only when the last descriptor is set.
(Bits 23 and 22 are not used, but reserved for backward compatibility and future expansion.)
19
RE Report on MII Error
When set, indicates that a receive error in the physical layer was reported during the frame
reception.
18
TL Frame Too Long
When set, indicates that the frame length exceeds the maximum size of 1518 bytes.
This bit is valid only when last descriptor is set.
Note: Frame too long is only a frame length indication and does not cause any frame
truncation.
17
RF Runt Frame
When set, indicates that this frame was damaged by a collision or premature termination
before the collision window has passed. Runt frames are passed on to the host only if the
pass bad frame bit is set.
16
CE CRC Error
When set, indicates that a CRC error occurred on the received frame.
This bit is valid only when last descriptor is set.
15
FT Frame Type
When set, indicates that the frame is an Ethernet-type frame (frame length field is greater
than 1500 bytes). When clear, indicates that the frame is an IEEE 802.3 frame.
This bit is not valid for runt frames.
This bit is valid only when last descriptor is set.
14 - 11
Reserved
10 - 0
FL Frame Length
Indicates the length, in bytes, of the received frame, including the CRC.
This field is valid only when last descriptor is set and descriptor error is reset.
