What does "typedef __u16 __bitwise __le16;" mean mean in the Linux kernel?

Question

What does typedef __u16 __bitwise __le16;the Linux kernel mean ?

in fact, what does le mean here? I vaguely see that this is an unsigned 16-bit int?

Thank you for your help.

.

typedef __u16 __bitwise __my_type1;
typedef __u16 __bitwise __my_type2;

Sparse , __my_type1 __my_type2.

with. __bitwise simply means order sensitivity, it does not indicate big-endian or little-endian.

I'm right?
