bool "Networking support"

---help---
Unless you really know what you are doing, you should say Y here.
The reason is that some programs need kernel networking support even
when running on a stand-alone machine that isn't connected to any
other computer.
-

If you are upgrading from an older kernel, you
should consider updating your networking tools too because changes
in the kernel and the tools often go hand in hand. The tools are
recommended to read the NET-HOWTO, available from
<http://www.tldp.org/docs.html#howto>.

+ help
+ This option makes it possible to send different netlink messages
+ to tasks depending on whether the task is a compat task or not. To
+ achieve this, you need to set skb_shinfo(skb)->frag_list to the
+ compat skb before sending the skb, the netlink code will sort out
+ which message to actually pass to the task.
+
+ Newly written code should NEVER need this option but do
+ compat-independent messages instead!

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 144 KB), since some programs (e.g. the X window
+ 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!).

- The Frame Diverter allows you to divert packets from the
- network, that are not aimed at the interface receiving it (in
- promisc. mode). Typically, a Linux box setup as an Ethernet bridge
- with the Frames Diverter on, can do some *really* transparent www
- caching using a Squid proxy for example.
-
- This is very useful when you don't want to change your router's
- config (or if you simply don't have access to it).
-
- The other possible usages of diverting Ethernet Frames are
- numberous:
- - reroute smtp traffic to another interface
- - traffic-shape certain network streams
- - transparently proxy smtp connections
- - etc...
