It is pretty unusual for ethernet drivers to export data in /sys,
except via standard APIs, like statistics, carrier, address, opstate
etc.  I don't know how well the core will handle EINTR. It is not
something most drivers do. -ETIMEDOUT is more likely when the firmware
has crashed and does not respond in time.

Do you have any operations which take a long time when things are
working correctly?
