[ Upstream commit 7255355a0636b4eff08d5e8139c77d98f151c4fc ]
Fix the current implementation that causes ice_trigger_vf_reset()
to start resetting the VF even when the VF-NIC is still initializing.
When we reset NIC with ice driver it can interfere with
iavf-vf initialization e.g. during consecutive resets induced by ice
iavf ice
| |
|<-----------------|
| ice resets vf
iavf |
reset |
start |
|<-----------------|
| ice resets vf
| causing iavf
| initialization
| error
| |
iavf
reset
end
This leads to a series of -53 errors
(failed to init adminq) from the IAVF.
Change the state of the vf_state field to be not active when the IAVF
is still initializing. Make sure to wait until receiving the message on
the message box to ensure that the vf is ready and initializded.
In simple terms we use the ACTIVE flag to make sure that the ice
driver knows if the iavf is ready for another reset
iavf ice
| |
| |
|<------------- ice resets vf
iavf vf_state != ACTIVE
reset |
start |
| |
| |
iavf |
reset-------> vf_state == ACTIVE
end ice resets vf

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.
