Some operations cannot be performed during the firmware flashing process. For example: - Port must be down during the whole flashing process to avoid packet loss while committing reset for example. - Writing to EEPROM interrupts the flashing process, so operations like ethtool dump, module reset, get and set power mode should be vetoed. - Split port firmware flashing should be vetoed. In order to veto those scenarios, add a flag in 'struct net_device' that indicates when a firmware flash is taking place on the module and use it to prevent interruptions during the process.

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 reStructuredText 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.
