Will fix.

Like stated in previous patch. The Nic DR define is of this format.

I'm not sure I understand your comment.
E-Switch rules are located in the device FDB, 
We can ether create E-Switch rules using tcf or using DR which are part of dv steering.
This parameters is used to select if the E-Switch rules engine will be the tcf or dv.

I agree and this is the default value, but since there are some basic initializations that are done for the E-Switch,
for example opening the name space, I can see that in some cases the user would like do disable this option.

It is the same indentation as all other cmd structures.
It is also a copy from the kernel and is based on automatic generation of the PRM.
