Just to annoy you :) [Sorry, couldn't resist.]

I'm sorry I didn't notice I was breaking the indent of the else branch. For some reason checkpatch didn't complain.

While at it, I'm also changing the netdev_info to netdev_err in vmxnet3_ethtool.c.

You didn't explicitly ask for it, so I wasn't sure if I should repost the patch. I'm going to repost it any way and leave it up to you on which patch you want to apply.

Thanks.
