[ Upstream commit 1f7fe5121127e037b86592ba42ce36515ea0e3f7 ]
The key length used when offloading macsec to Ethernet or PHY drivers
was set to MACSEC_KEYID_LEN (16), which is an issue as:
- This was never meant to be the key length.
- The key length can be > 16.
Fix this by using MACSEC_MAX_KEY_LEN to store the key (the max length
accepted in uAPI) and secy->key_len to copy it.

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.
