base offset. if the valuetype is U8 the offset can be odd or even.
If the ValueType is U16, U32 or U64 then the offset can only be
even. This field is not valid for any other value type.
Mask
Mask, used to select the individual bits to be matched in a
packet. If ActVal is SetBase and SBaseType is Compute then
this value is used to specify the mask, which shall be used to
identify the individual bits of the field of the packet used to
compute the new base offset. This field is valid only if the
ValueType is U8, U16, U32 or U64. This field is also valid if the
ActVal is MatchInGenList.
Value
Value, to be matched. For NonLinear node types, this field is not
valid. For Linear node types, this value is used to specify the
start of the range. if ActVal is SetBase and SBaseTypeis
Compute then this field is used to specify the value,
which is to be added to base offset to calculate new base offset.
If the ActVal is SetPrio or RetagPrio then this field is used to
specify the priority which is to be assigned to the packet. If the
ActVal is MatchInGenList then this field is not
valid. If the ActVal is Count then this field is read only and
specifies total number of octet of the packets hitting this node.
Value End
For Linear nodes this field is used to specify the end of the
range. If the ActVal is InRange then this field is used to specify
the end of the range. If the ActVal is count then this field is used
to specify the total number of packet hitting this node. For other
actions this field is not valid.
Set Base type
SetBaseType is used to specify whether the base off set is to be
set to an absolute value, or some value is to be added to existing
base offset value to calculate new base offset value or the new
base offset value is to be computed using some value in the
packet. This field is valid only if the ActVal is SetBase.
Shift Count
ShiftCount, is the number of times the Value in the packet is to
be shifted before multiplying it with the Mplr. This field is valid
only if the ActVal is SetBase. Value 32 is used to set shift count
to an invalid value.
Multiplier
Multiplier is used to multiply the value shifted by ShiftCount. It is
used to calculate the new base offset. This field is valid only if
the ActVal is SetBase.
Description
Description of the profile node. If the ActVal is FwdToCtl or
CpToCtl then this field is mandatory and it can be used by the
applications to receive the packets coming from control plane
