It sounds good to mark the global netns variable as 'readonly', but Bash doesn't allow the creation of local variables with the same name. Because it looks like 'readonly' is mainly used here to check if a netns with that name has already been set, it sounds fine to check if a variable with this name has already been set instead. By doing that, we avoid having to modify helpers from MPTCP selftests using the same variable name as the one used to store the created netns name. While at it, also avoid an unnecessary call to 'eval' to set a local variable.

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 reStructuredText 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.
