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).

A small formatting issue, perhaps you're using spaces?

Can HOMA run in an environment without IPv6（IPv4 only)? If so, depends is not suitable here. Perhaps
what you need is to implement different branches in the code using
#if IS_ENABLED(CONFIG_IPV6)

+ 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.
