Sorry for the late reply, I tested my patch on mips, arm, arm64 and x86 and
it works everywhere, but for arm64 I had to add extra functions, because
it doesn't use the GCC __builin for swapping bytes. I have extended the
plugin and will send a new version.

On mips using network order ntohs (and similar) expands to a cast only, so
the call to swap is not present.
