Description
Reserved
Byte Offset
When this rule matches, do not attempt another match for this number of
bytes. A zero means that the very next byte will be executed. A value of
one means that the very next packet byte is ignored but the byte after
that is executed, etc. When this field is used to initialize the counter, no
offset is applied (see the TOC Control Logic Action).
Reserved
Interrupt
When a match is made for this rule then trigger an interrupt to the host.
Control Logic Action
Specifies what action to take when a match is made.
The Control Logic Actions are described in detail in
0x0 = NOP
0x2 = PAUSE
0x4 = WAKE
0x6 = IPCK
0x7 = TIPO
0x8 = TDX
0xA = TAX
0xC = TAXH

0x12 = TLXA
Description
Previous Hit Mask
Mask bits to match for the previous hit match. A zero means the
corresponding bit in the previous hit match does not have to match to
be a hit.
Reserved
Previous Hit Match
This CAM entry matches against the address of the previous CAM hit.
Reserved
Data Mask
Mask bits to match for the data match. A zero means the
corresponding bit in the data match does not have to match to be a hit.
Data Match
This CAM field matches against either the packet byte or the control
logic ‘X’ register value selected by the match control field of the control
word register.
