commit7f04839ec4upstream. Initial FLOGIs are failing with the following message: lpfc 0000:13:00.1: 1:(0):0820 FLOGI Failed (x300). BBCredit Not Supported In a prior patch, the READ_SPARAM command was re-ordered to post after CONFIG_LINK as the driver is expected to update the driver's copy of the service parameters for the FLOGI payload. If the bb-credit recovery feature is enabled, this is fine. But on adapters were bb-credit recovery isn't enabled, it would cause the FLOGI to fail. Fix by restoring the original command order (READ_SPARAM before CONFIG_LINK), and after issuing CONFIG_LINK, detect bb-credit recovery support and reissuing READ_SPARAM to obtain the updated service parameters (effectively adding in the fix command order).

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.
