From: Vaishali Thakkar <vthakkar1994@xxxxxxxxx>
In little endian cases, the macro htons unfolds to __swab16 which
provides special case for constants. In big endian cases,
__constant_htons and htons expand directly to the same expression.
So, replace __constant_htons with htons with the goal of getting
rid of the definition of __constant_htons completely.
The semantic patch that performs this transformation is as follows:
@@expression x;@@
- __constant_htons(x)
+ htons(x)
