Subject: [PATCH net-next] net: cavium: add missing PCI dependencies

While some of the cavium drivers don't require PCI support, most
others do, as shown by these build failures:

This adds back the minimum set of dependencies to get everything to
build cleanly again, but leaving the ones that build cleanly.

I believe this hunk should look exactly as the previous one, i.e. 64BIT && PCI,
BGX itself depends on PCI as well. I've actually sent v2 to fix the above, but
got no reply on it up to now...

Hi Arnd

FYI

There is a 0-day email about mdio-thunder.c also failing. It looks
like a missing PCI dependency as well, although i cannot find the
patch which removed the existing dependency.

there were no such patch, some Ethernet driver not depending on PCI
forcefully selected MDIO_THUNDER. So this is only a side effect of the
first error.

Ah, O.K. Thanks for the explanation.

That would work as well. My approach was to allow compiling that driver
with PCI because I got no build failures other than the MDIO_THUNDER
issues.

Your patch was applied into net-next already, so you need to send
a fix relative to your first patch rather than a replacement.

Applied, thanks Arnd.
