Subject: [RFC PATCH v3 net-next 01/10] net: dsa: ocelot: remove unnecessary pci_bar variables

The pci_bar variables for the switch and imdio don't make sense for the
generic felix driver. Moving them to felix_vsc9959 to limit scope and
simplify the felix_info struct.

I distinctly remember giving a Reviewed-by tag for this patch in the
previous series:

https://patchwork.kernel.org/project/netdevbpf/patch/[email protected]/

It would be nice if you could carry them along from one series to the
next so we don't have to chase you.

If you use git b4 when you start working on a new version, the extra
tags in the comments are downloaded and appended automatically. That is
if you are not ok with manually copy-pasting them into your commit
message.

Yes, you did. I'll do that next time. Forgive me, for this entire
process is very much a learning experience for me.
