The current implementation relies on H_IOCTL call to issue a H_SESSION_ERR_DETECTED command to let the hypervisor to send a failover signal. However, it may not work if there is no backup device or if the vnic is already in error state, e.g., "ibmvnic 30000003 env3: rx buffer returned with rc 6". Add a last resort, that is to schedule a failover reset via CRQ command. Signed-off-by: Lijun Pan <lijunp213@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
