 LCO is a technique for efficiently computing the outer checksum of an
  encapsulated datagram when the inner checksum is due to be offloaded.
 The ones-complement sum of a correctly checksummed TCP or UDP packet is
- equal to the sum of the pseudo header, because everything else gets
- 'cancelled out' by the checksum field.  This is because the sum was

  complemented before being written to the checksum field.
 More generally, this holds in any case where the 'IP-style' ones complement
  checksum is used, and thus any checksum that TX Checksum Offload supports.
 That is, if we have set up TX Checksum Offload with a start/offset pair, we
- know that _after the device has filled in that checksum_, the ones

 Then, when the true inner checksum is filled in (either by hardware or by
  skb_checksum_help()), the outer checksum will become correct by virtue of
  the arithmetic.
