Hi Experts,

Does anyone knows how to disable TCP Offloading on DD-WRT?

Mine is running  "DD-WRT v24-sp2 (08/07/10) std" and the box didn't provide any ethtool utility.

Thanks

There is no TCP Offloading in DD-WRT that I'm aware of... who told you there is?
DD-WRT is built with a linux kernel, and the last I heard all the linux kernel devs were opposed to building support for hardware TCP Offloading into the kernels.

Hi Darr247, thanks for that info. the reason why I ask the question is when I run tcpdump on the DD-WRT, I can see that there are checksum occurring.

What interface are you dumping?

It seems to me if you're seeing chksum's, that means the interface is calculating them... that function's not being offloaded to anything else.
