ng_checksum

New node can calculate IP IP6 TCP UDP checksum, prepare for hardware offloading calculate checksum.

It can be used for example with ng_patch.
Comment 1 Dmitry Wagin 2016-01-13 09:45:09 UTC 
example use (with ng_patch):

 ngctl msg patch-1: "setdlt 1"
 ngctl msg checksum-1: "setdlt 1"

 ngctl msg ${_NAME}-patch-1: "setconfig { count=4 csum_flags=1 relative_offset=1 ops=[ \
   { mode=7 value=0x03 length=1 offset=1 } \
   { mode=8 value=0x88 length=1 offset=1 } \
   { mode=1 value=30120 length=2 offset=22 } \
   { mode=1 value=0 length=2 offset=26 } \
  ] }"

= set checksum flag CSUM_IP, set DSCP, set UDP port 30120, set UPD checksum = 0

 ngctl msg checksum-1: "setconfig { csum_flags=0 csum_offload=6 }"

= not sed additional checksum flags, set hardware can calculate CSUM_IP_UDP|CSUM_IP_TCP.
