Enable networking options required for NFS boot on TI platforms, which is
widely for automated test systems.
- enable new TI CPSW switch driver and related NET_SWITCHDEV config
- enable TI DP83867 phy
- explicitly enable PTP clock support to ensure dependent networking
drivers will stay built-in

Are there any actions need to be done to have this patch merged?

I would prefer if a platform maintainer (I assume Tony in this case)
picks it up and forwards it to soc@kernel.org together with other
related changes. Olof and I tend to ignore patches sent directly
to us, so we don't get in the way of platform maintainers that
may have already merged similar patches or have comments.

I suspect Tony didn't pick it up either because from the patch
subject and the description, it is not clear that he is the one
to act on it. It helps to be more specific and ask the maintainer
by addressing them in person below the '---' line, as well as
only putting one person in 'To:' and the rest in 'Cc:'.

One comment on the contents of the patch: IIRC this is a fairly
large driver. To ensure we don't burden other users too much,
can you include the size of the vmlinux file before and after
this patch?

Thanks for your comments and sorry that I disturbed you.

But, honestly, I'm confused (and probably I'm not the first one) as multi_v7 is common
for all ARM platforms while change is TI OMAP specific,
and neither Documentation neither get_maintainer.pl provide any reliable information
on how to proceed :( and who should be responsible for merging multi_x patches.

I'd really have tried to do some checking while preparing patch and TO/CC list - some patches applied by
platform maintainers, but some by top ARM maintainers.

I understand that this is confusion, and we should probably come up
with a better way to handle it.

To clarify further, while we prefer the patches to be picked up by the
platform maintainers and forwarded to us for patches to the common
files that are needed for a particular platform, you can also send these
patches directly to soc@kernel.org, which puts them into patchwork
at https://patchwork.kernel.org/project/linux-soc/list/. Once it's in
there, we will process it by merging the patch or getting back to you
for further clarification.

Ok, that doesn't look too bad, though the total size is definitely worrying.
Please include the above in the changelog text.
