AW: [e2e] Question about fast path / slow path and IPv6

[Michael Welzl]

Hi Ran,

Thanks for your answer! I figure I was too imprecise ...

what I meant was:

> Other products cannot do so -- in which case only packets without
> options are "fast path" and packets with options are "slow path".
> This last case includes all (or nearly all) routers that use
> CPU-based packet forwarding.

... in these cases, does it make a difference if I use
IPv4 or IPv6?

Cheers,
Michael
