RL-ARM TCP-net ICMP Checksum Offload on STM32F4

chuck m

I am wondering if it is possible to enable RL-ALM TCP-net to use the STM32F4 checksum offload capability for ICMP responses.

The offload capability works well for UDP/TCP because I can tell TCP-net to not generate these checksums. However, I can't find how to similarly instruct the ICMP portion of TCP-net to use the offload capability. As a consequence, when this feature is enabled, TCP-net computes the checksum and then the STM32F4 zeroes the checksum due to recomputing it.

I'd like to be able to turn off the code in TCP-net for the ICMP checksum computation and rely only on the hardware.

Any help is greatly appreciated.

Thanks
