Hi David,

This patch is failing in the travis for ABI checks [1], since mlx has APIs now
[2], are they public APIs or internal ones, and are they part of the ABI policy,
can you please check this?

@Thomas, please don't pull from next-net until this resolved, since this patch
is merged into next-net.

Thanks,
ferruh
