Hi, We are adding the TCP Segmentation offload (TSO) support to the device driver and the hardware. I am wondering: Can Linux subsystem supports the use of IP options and TCP options? If so then which options (e.g SACK processing for TCP)? Do we need any implementation in the NIC to manage TCP/IP options? Thanks, Sedat

Hi, On TSO and TCP options, as far as I tested approx. 10 NICs, TSO copies TCP options to all the split segments. (We performed this test for Timestamp and an undefined option). This paper (http://nrg.cs.ucl.ac.uk/mjh/tmp/mboxes.pdf) would be helpful. Thanks, - Michio On Sep 27, 2011, at 4:19 PM, Sedat Cakir wrote:
