THXA
The high-order nibble of the classification result is assigned the value of
the high-order nibble value of ‘X’.
0x15
10101b
SETMC
Mark the frame as multicast for Rx statistics purposes.
0x16
10110b
VLAN
Mark the frame as VLAN tagged for length checking and statistics.
0x17
10111b
SETBC
Mark the frame as broadcast for Rx statistics purposes.
0x18

TOC
The control logic counter value is initialized to the value contained in the
Byte Offset field. No offset is applied.
0x1A
11010b
DEC
The control logic counter value is decremented. If the counter has
reached zero then the control logic will decrement the previous hit value
used to generate the next CAM reference word by one.
0x1B
11011b
MCTL
Classify the frame as a MAC control frame. This also sets the Len/Type
LSB.
0x1C
11100b
TDPH
The pause counter most significant byte is set from the frame data.
0x1D
11101b
TDLTH
The Len/Type most significant byte is set from the frame data.
0x1E
11110b
TDPL
The pause counter least significant byte is set from the frame data.
0x1F
11111b
TDLTL
The Len/Type least significant byte is set from the frame data.
RCR Match Control
The value of the Match Control field will determine how the control logic generates the next CAM
reference word.

Value

Action Taken
00b
DONE
No more CAM reference words are generated. No further classification is
done for the current frame.
10b
MD
The next frame data is used to generate the next CAM reference word.
01b
MX
The ‘X’ value is used in place of the frame data to generate the next CAM
reference word.
11b
DROP
Drop the frame. If this is executed within the first 128 bytes of the frame
then the entire frame is dropped from the QUE. No more CAM reference
words are generated.

Frame Format
The following table shows the format of an Ethernet frame. The fields are in the order that the
classification engine sees them, from left to right. The byte count for each field is specified on the bottom
row of the table.

If the Len/Type field contains a 16-bit value that is less than 0x0600, the field is interpreted as a length
field that specifies the number of bytes in the User field. If the value is greater than or equal to 0x0600,
the type interpretation is to be used.
