dear all,
i want to offload ip checksum calculation to the NIC.
I use 3Com 3c905B-TX NIC cards.
I found that there are variables::>>
int csum_flags; /* flags regarding checksum */
int csum_data; /* data field used by csum routines */
in struct pkthdr in mbuf.h.
also i found the various flags for the hardware checksumming.
but i don't know the exact steps i need to do
in order to offload checksumming.
should i set the csum_flags to CSUM_IP and point
csum_data to the start of the ip header ??
it would be a great help if anybody
could tell me what do i need to do ?
thanks,
kamal
