When run test_tc_tunnel.sh, it complains following error
ipip
encap 192.168.1.1 to 192.168.1.2, type ipip, mac none len 100
test basic connectivity
nc: cannot use -p and -l
nc man page has:
-l Listen for an incoming connection rather than initiating
a connection to a remote host.Cannot be used together with
any of the options -psxz. Additionally, any timeouts specified
with the -w option are ignored.
Correct nc in server_listen().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
