254  * Immediate length field specifies size of write.  R must be 0.  imm_len != 0.
262  * R=0 means copy from packet.
263  * R=1 means copy from APF program/data region.
286  * R=0: register R0 specifies the length
287  * R=1: length provided in u16 imm2
294  * R=1 iff udp style L4 checksum
313  * R=0 means copy from packet.
314  * R=1 means copy from APF program/data region.
323  * R=0/1 meaning 'does not match'/'matches'
337  * R=0/1 meaning 'does not match'/'matches'
348  * R bit - specifies the register (R0/R1) to test
