TensorRT custom plugin set input format as kCHW4, but get NHWC data

Description

I wrote a custom plugin and set supported format as kCHW4 in supportsFormatCombination function.
However, when I check the input data, I found the input data format is actually NHWC, but not NC1HWC0, where C1=C/C0, and C0=4.
While If I set supported supported format as kCHW2, I get NC1HWC0 data, where C1=C/C0, and C0=4.
So kCHW4 do not the NC1HWC0 rules?
