Does STM32F427/29 supports hardware checksum for fragmented TCP/UDP/ICMP packets?

  • I have enabled hardware checksum in STM32F427 it works fine for all packet except when it deals with fragmented packet. In wireshark I see checksum error for fragmented UDP packet and it maybe caused by "UDP checksum offload".
  • In reference manual of STM32F427/29, it was mentioned that Fragmented IP frames (IPv4 or IPv6), IP frames with security features (such as an authentication header or encapsulated security payload), and IPv6 frames with routing headers are bypassed and not processed by the checksum.
  • Any solution for fragmented packet?
