Hello,
I'm trying to use the TCP&IP checksum offload capability of the Netgear
GA620 NIC from a SMP FreeBSD 4.2R system running on a typical PIII SBC.
I did enable TCP&IP cksum offload for receive operations by setting the
if_hwassist flag in the driver /sys/pci/if_ti.c and verified that it is
working. However I'm unable to offload TCP&IP checksum for the send
operations.
For the send operation, I see that the kernel is still doing the TCP and IP
checksum calculations although the driver has the hw_assist flag set.
Can you please let me know what else needs to be done to offload TCP and IP
checksum for both rcv/send operations on the Tigon2 NIC?
Thanks,
-Srinivas
