When the NCSI driver is stopped with ncsi_stop_dev() the channel monitors are stopped and the state set to "inactive". However the channels are still configured and active from the perspective of the network controller. We should suspend each active channel but in the context of ncsi_stop_dev() the transmit queue has been or is about to be stopped so we won't have time to do so. Instead when ncsi_start_dev() is called if the NCSI topology has already been probed then call ncsi_reset_dev() to suspend any channels that were previously active. This resets the network controller to a known state, provides an up to date view of channel link state, and makes sure that mode flags such as NCSI_MODE_TX_ENABLE are properly reset. In addition to ncsi_start_dev() use ncsi_reset_dev() in ncsi-netlink.c to update the channel configuration more cleanly.

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.
