Since this is a network device, you might want to take a look at
devlink support for flashing devices.

https://www.kernel.org/doc/html/latest/networking/devlink/devlink-flash.html

And for collecting crashes and other health information, consider
devlink region and devlink health.

It is much better to reuse existing infrastructure than do something
proprietary with a char dev.
