Linux kernel source tree

There is a bug in handling the possible return codes from sending the login CRQ. The current code treats any non-success return value, minus failure to send the crq and a timeout waiting for a login response, as a need to re-send the login CRQ. This can put the drive in an infinite loop of trying to login when getting return values other that a partial success such as a return code of aborted. For these scenarios the login will not ever succeed at this point and the driver would need to be reset again. To resolve this loop trying to login is updated to only retry the login if the driver gets a return code of a partial success. Other return codes are treated as an error and the driver returns an error from ibmvnic_login(). To avoid infinite looping in the partial success return cases, the number of retries is capped at the maximum number of supported queues. This value was chosen because the driver does a renegotiation of capabilities which sets the number of queues possible and allows the driver to attempt a login for possible value for the number of queues supported.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
