Andrea Righi a985442fde selftests: net: properly support IPv6 in GSO GRE test
Explicitly pass -6 to netcat when the test is using IPv6 to prevent
failures.

Also make sure to pass "-N" to netcat to close the socket after EOF on
the client side, otherwise we would always hit the timeout and the test
would fail.

Without this fix applied:

 TEST: GREv6/v4 - copy file w/ TSO                                   [FAIL]
 TEST: GREv6/v4 - copy file w/ GSO                                   [FAIL]
 TEST: GREv6/v6 - copy file w/ TSO                                   [FAIL]
 TEST: GREv6/v6 - copy file w/ GSO                                   [FAIL]

With this fix applied:

 TEST: GREv6/v4 - copy file w/ TSO                                   [ OK ]
 TEST: GREv6/v4 - copy file w/ GSO                                   [ OK ]

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.
