fixes

these drivers.
The idea behind putting out this series is to either establish that
these
drivers are used and should be maintained, or remove them.
Anirudh,
The Sun LDOM vswitch and sunvnet drivers are still in use, please do
not remove them or the event tracing.
We use them internally and you don't see any discussions because they
generally work fine (AFAIK).
Hello Karl,
Thanks for chiming in.
Are there recent platforms where these drivers are used? If yes, do
you know which ones? Or are these drivers useful in old/legacy
platforms that are still around but perhaps no longer in production?
These drivers work on older T4, T5, etc to the latest T7, T8 Sun
servers (e.g. T8-2, T8-4, note, T7/T8 are still in production).
They may also work on T2/T3 (but I don't use those anymore, though
Adrian (John Paul Adrian Glaubitz <glaubitz@xxxxxxxxxxxxxxxxxxx>) might).
You might have missed a lot of the linux SPARC developers since they are
on the debian-sparc@xxxxxxxxxxxxxxxx list, hence I'd ask there also.
I think you are also going to break things by removing Sun Cassini
support, but I am not using it personally.
You suspect there are users for this driver as well?
Yes, they may not have seen this yet or recognized the servers this card
goes in (post on debian-sparc@xxxxxxxxxxxxxxxx list).
What user visible bugs are you referring to here?
I was saying I don't see any evidence of recent bug fixes, which would
make sense if these drivers "just work".
ok, no worries.
Cheers
Karl
