Here ERROR_ID is provided and ERROR_VALUE is returned, but maybe we can 
return also ERROR_NAME for the "full picture"?
Or do you think that a regular flow would be first listing all errors, 
grep the name of the required error, and use its id to get the value, so 
userspace already has the name?

It is really possible that NLMSG_DEFAULT_SIZE won't be enough for a 
single counter read?

Thanks,
