Some FC adapters from Marvell offer the ability to encrypt data in flight (EDIF). This feature requires an application to act as an authenticator. There is no FC switch scan service that can indicate whether a device is secure or non-secure. In order to detect whether the remote port supports encrypted operation, driver must first do a PLOGI with the remote device. On completion of the PLOGI, driver will query firmware to see if the device supports secure login. To do that, driver + firmware must advertise the security bit via PLOGI's service parameter. The remote device shall respond using the same service parameter whether it supports it or not.

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.
