The value of GET_RX_DESC_SWDEC() indicates that if this RX packet requires software decryption or not. And software decryption is required when the packet was encrypted and the hardware failed to decrypt it. So, GET_RX_DESC_SWDEC() is negative does not mean that this packet is decrypted, it might just have no encryption at all. To actually see if the packet is decrypted, driver needs to further check if the hardware has successfully decrypted it, with a specific type of encryption algorithm.

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.
