Re: TSO support

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,

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
