Subject: [PATCH] Change to calling bswap_* instead of htobe* and be*toh

We can't use htobe* and be*toh functions because they are not
available on older versions of glibc, For example, shipped on Centos 5.5.

Change to directly calling bswap_* as defined in+byteswap.h.

Upstream-Status: Inappropriate
