During an uplink toggle test all error handling is done via timeout and firmware error conditions which can occur concurrently: - SCSI layer timeouts - Error detect CQEs - Firmware detected underruns - ABTS timeouts All these concurrent events require more defensive checks in the driver including: - Check both internally and externally generated aborts to make sure the xid is not already been aborted in another context or in cleanup. - Check back pointers in qedf_cmd_timeout to verify the context of the io_req, fcport and qedf_ctx - Check rport state in host reset handler to not reset the whole host if the rport is already uploaded or in the process of relogin - Check to state for an fcport before initiating a middle path ELS request Signed-off-by: Chad Dupuis <chad.dupuis@cavium.com> Signed-off-by: Martin K.

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.
