CSLIP compressed headers

configname: CONFIG_SLIP_COMPRESSED

Linux Kernel Configuration
└─>Networking support
└─>CSLIP compressed headers
In linux kernel since version 2.6.12  
This protocol is faster than SLIP because it uses compression on the
TCP/IP headers (not on the data itself), but it has to be supported
on both ends. Ask your access provider if you are not sure and
answer Y, just in case. You will still be able to use plain SLIP. If
you plan to use SLiRP, the SLIP emulator (available from
<ftp://ibiblio.org/pub/Linux/system/network/serial/>) which
allows you to use SLIP over a regular dial up shell connection, you
definitely want to say Y here. The NET-3-HOWTO, available from
<http://www.tldp.org/docs.html#howto>, explains how to configure
CSLIP. This won't enlarge your kernel.
