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 _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
