MACSEC_SA_ATTR_PN is either a u32 or a u64, we can now use NLA_UINT
for this instead of a custom binary type. We can then use a min check
within the policy.
We need to keep the length checks done in macsec_{add,upd}_{rx,tx}sa
based on whether the device is set up for XPN (with 64b PNs instead of
32b).
On the dump side, keep the existing custom code as userspace may
expect a u64 when using XPN, and nla_put_uint may only output a u32
attribute if the value fits.

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.
