Hello Juliana,
There are many PCH2 devices with different SKU's.  Not all devices have 
this problem (Tx hand). We do not want to set disabling TSO as the 
default version. Let's keep this option for all other users.
Also, this is very old known HW bug - unfortunately we didn't fixed it. 
Our more new devices have not this problem.
