Modifying DNP3 Content

[Chamara Devanarayana via Snort-devel <snort-devel () lists snort org>]

Hi,
I tried to use SNORT inline to modify DNP3 application data. Although SNORT modified the data it did not modify the CRC 
which is there after the first 8 bytes and then after each 16 bytes. Therefore, there was a CRC error at the DNP3 
Master. I modified the sp_replace to handle this and it was working after that. Is it possible to contribute the 
changes that I made in the SNORT repo? If so what is the procedure for doing so?
Thanks,
Best regards,
