Subject: [PATCH] netvsc: Remove redundant use of ipv6_hdr()

This condition already uses an object of type ipv6hdr in the line above.
Use the object directly instead of calling ipv6_hdr

Patch looks fine.
Network patches go through [email protected] not linux driver mailing list.
I will add it to my next patch of patches that are going to netdev for net-next.

Thanks for the heads up. Will take that into consideration next time.

It's worth pointing out that MAINTAINERS points that files under
drivers/net/hyperv are to be sent to [email protected].
Perhaps that should be updated.

MAINTAINERS doesn't have a good way to handle dual sub-trees.

I will update [email protected] in MAINTAINERS to the new
mailing list name of the Linux driver project.

get_maintainer.pl gives you both because drivers/net/ is netdev. Just
use the script.
