  The udp_ip4_ind bit is set only for IPv4 UDP non-fragmented packets
  so that the hardware can flip the checksum to 0xFFFF if the computed
  checksum is 0 per RFC768.

  However, this bit had to be set for IPv6 UDP non fragmented packets
  as well per hardware requirements. Otherwise, IPv6 UDP packets
  with computed checksum as 0 were transmitted by hardware and were
  dropped in the network.

  In addition to setting this bit for IPv6 UDP, the field is also
  appropriately renamed to udp_ind as part of this change.

• 9395da4ef   net: qualcomm: rmnet: Move common struct definitions to include ... Browse Code »

  Create if_rmnet.h and move the rmnet MAP packet structs to this
  common include file. To account for portablity, add little and
  big endian bitfield definitions similar to the ip & tcp headers.

  The definitions in the headers can now be re-used by the
  upcoming ipa driver series as well as qmi_wwan.
