Normally, if a reset fails due to failover or other communication error there is another reset (eg: FAILOVER) in the queue and we would process that reset. But if we are unable to communicate with PHYP or VIOS after H_FREE_CRQ, there would be no other resets in the queue and the adapter would be in an undefined state even though it was in the OPEN state earlier. While starting the reset we set the carrier to off state so we won't even get the timeout resets. If the last queued reset fails, retry it as a hard reset (after the usual 60 second settling time).

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.
