Hello !

Thanks for sending this. I have one question regarding the Yosemite board that you have. What is the version of the Titan chip on the board? Is it 1.0, 1.1 or 1.2?

This is because 1.0 and 1.1 have a problem where the IP header is not aligned on the Rx side. As a result, there was an extra copy involved in the driver, i.e. titan_ge_slowpath. The latest version of the driver only support Titan chip revision 1.2 in which this problem is fixed

Thanks
