31  This option is only valid for L2/L3 input ACL for now.
32  0: by default, classify data from the buffer's start location
33  1: classify packets from VPP node’s current data pointer

35  the packet to be classified
36  For example, if input IP ACL node is used, L2 header’s first byte
37  can be accessible by configuring current_data_offset to -14
38  if there is no vlan tag.
39  This is valid only if current_data_flag is set to 1.
