I truly dislike adding networking protocols that depend upon some
piece of infrastructure that only some platforms can enable, it's even
worse when that set of platforms doesn't intersect with x86-64.

When you do things like this, it's quite hard to make protocol wide
changes to APIs because build testing becomes an issue.

This code can now only be build tested on ARCH_QCOM architectures, and
that's a serious negative downside.
