When the link goes down, we need to disable the queues on the NIC in addition to stopping the netdev stack. This lets the FW know that the driver has stopped queue activity, and then the FW can do internal reconfiguration work, whether actually Link related, or for other internal FW needs. To do this, we pull out the queue enable and disable from ionic_open() and ionic_stop() so they can be used by other routines. To help keep things sane, we swap the queue enables so that the rx queue and its napi are enabled before the tx queue which rides on the rx queues napi. We also drop the ionic_lif_quiesce() as it doesn't do anything more than what the queue disable has already taken care of. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S.

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.
