Network drivers need to use reverse christmas tree. I spotted a number
of functions getting this wrong. Please review the whole driver.

I expect checkpatch complained about this. Don't use pr_err(), use
dev_err(pdev->dev, ...  of netdev_err(ndev, ... You should always have
access to dev or ndev, so please change all pr_ calls.

No module parameters please.
