user_define_mask
Specifies the L4 part mask.
packet_content_mask
Specifies the frame content mask. There are a maximum of five offsets
that can be configured.
Each offset presents 16 bytes, the range of mask of frame is 80 bytes (5
offsets) in the first eighty bytes of frame.
offset
Specifies the mask pattern offset of frame.
offset_chunk_1,
offset_chunk_2,
offset_chunk_3,
offset_chunk_4
