FreeBSD 5.0-current has support for TCP/IP checksum offload, and the if_ti driver makes use of it. The Tigon NICs do this in firmware though. I attempted to add support to the SysKonnect driver, however the transmit side checksum offload support apparently doesn't work, and the receive side offloading has a bug which requires a bit of a workaround. The 3Com 3c90xB/3c90xC chips are also supposed to support checksum offload, but as of yet I haven't had much luck getting this to work either. -Bill To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
