This mask will be applied to the identification key before a
CRC is applied to it. When ‘0’, the corresponding bit in the
identification key will be masked to ‘0’. When the
identification key is only 4 dwords long, dwords 4 - 9 in this
mask are ignored.
Indicates what to do when the hardware encounters these
option values.
“00” = unknown/no decision;
“01” = skip to end;
“10” = CPU through fragmented IP;
“11” = delete.
Each profile entry contains the treatment values for Options
N*16 to N*16+15, where N is the profile entry number. In
this way, all 256 values for the options are treated. These
values are not in any way linked to the profile; they just
reside in the same memory.
