Hi,
I am changing the inbound data on a kpi_ipfilter. I need to redo the checksum so the packet is not thrown away.
I have been told there is a method in the kernel that can calculate the checksum by passing in the mbuf reference or it was an unsigned char array.
Does anyone know where this might be? This was on 10.3, so is there one available on Tiger I could use?
Thanks,
Matt
