The notification should probably be for removal in 17.08, to one release cycle to respond/fix/update.

It would also be good to hear from EZChip/Mellanox on this.

There were some previous messages/warnings and there were no answer.
I have asked a working free toolchain, I did not have it.
We have asked some questions about drivers support, no reply.
I have asked about removal, no reply.
I really do not see why we should keep it longer.

> It would also be good to hear from EZChip/Mellanox on this.

They are mute since a long time on this topic.
Olga, do you confirm?

Regretfully, I must agree with Thomas on this. In the absense of a
response from someone to maintain this, it should be removed.

If - as seems likely - this deprecation notice makes it into the 17.02
release, I would just ask that the actual removal of the code *not* take
place at the start of the 17.05 release cycle, to be sure to give
further additional grace period for someone to respond to this. I think
it is only fair to wait till just before the RC's are produced to remove
the code, given it is such a drastic step, and the official notice of
removal is only inserted right before 17.02 goes out.

Hi,

That seems like a fair compromise.

It does for me:

As suggested by Bruce, let's remove it just before v17.05-rc1 to
let some time, even if they would already have replied in case they
had a plan for maintaining it.
