Subject: [PATCH] net: don't allow INET to be not configured

There is no reason to expose turning off TCP/IP networking.
If networking is enabled force TCP/IP to enabled. This also
eliminates the time chasing down errors with bogus configurations
generated by 'make randconfig'

For testing, it is still possible to edit Kconfig

-	  These are the protocols used on the Internet and on most local
-	  Ethernets. It is highly recommended to say Y here (this will enlarge
-	  your kernel by about 400 KB), since some programs (e.g. the X window
-	  system) use TCP/IP even if your machine is not connected to any
-	  other computer. You will get the so-called loopback device which
-	  allows you to ping yourself (great fun, that!).

-	  For an excellent introduction to Linux networking, please read the
-	  Linux Networking HOWTO, available from
-	  <http://www.tldp.org/docs.html#howto>.
-
-	  If you say Y here and also to "/proc file system support" and
-	  "Sysctl support" below, you can change various aspects of the
-	  behavior of the TCP/IP code by writing to the (virtual) files in
-	  /proc/sys/net/ipv4/*; the options are explained in the file
-	  <file:Documentation/networking/ip-sysctl.txt>.
-
-	  Short answer: say Y.
