--- Comment #17 from Goran Meki=C4=87 <meka@tilda.center> ---
I remember a discussion (probably mailing list) that tackled this problem, =
and
one of the questions that was raised was ABI compatibility. There were 2
proposals:
  1. Add new uint64_t var which would be used in higher bandwidth configs
  2. Use current variable non-linearly: up to (I'm making an example) 1Gb/s
it's linear, and then it's some other curve.

I'm sorry I can't find it in lists archives so we could have a proper
reference. I might be wrong about the exact proposals, so don't trust me
blindly, but the overall idea of the two proposals is correct.
