[PATCH net-next v4 05/10] include: netdevice: Add module firmware flashing in progress flag to net_device

From: Danielle Ratson
Date: Thu Apr 18 2024 - 06:37:20 EST


Some operations cannot be performed during the firmware flashing
process and will be vetoed later in the patchset.
For example, flashing firmware on a device which is already in a flashing
process should be forbidden.

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.
