[PATCH net-next v2 12/12] net: homa: create Makefile and Kconfig

[John Ousterhout <ouster@cs.stanford.edu>]

Before this commit the Homa code is "inert": it won't be compiled
in kernel builds. This commit adds Homa's Makefile and Kconfig, and
also links Homa into net/Makefile and net/Kconfig, so that Homa
will be built during kernel builds if enabled (it is disabled by
default).

+	Homa is a network transport protocol for communication within
+	a datacenter. It provides significantly lower latency than TCP,
+	particularly for workloads containing a mixture of large and small
+	messages operating at high network utilization. For more information
+	see the homa(7) man page or checkout the Homa Wiki at
+	https://homa-transport.atlassian.net/wiki/spaces/HOMA/overview.
+
+	If unsure, say N.
