You should always check the networking -stable queue before asking
such questions:

	http://patchwork.ozlabs.org/bundle/davem/stable/?submitter=&state=*&q=&archive=

Every patch sitting there is queued up and will be submitted to -stable
at some time in the next week or two, or whenever I get around to vetting
and submitting -stable changes.

The patch you are asking about it in fact in there, and will be attended
to at an appropriate time.

Thanks.

Thank you David for prompt reply. I guess perhaps you are not aware that 
patches to stable line 4.8 might not be accepted after Sun Jan 8th 
(yesterday), and it will be considered EOL by version 4.8.17 ?

Best regards

It's ok, no one should be using 4.8 anymore now, and if this is fixed in
4.9, all is good :)

4.8 will be end-of-life on Monday (tomorrow), so I doubt this means
much, but please remember, for networking patches, the networking
maintainer is the one that sends them to me, so you need to ask this
type of thing on the netdev mailing list.

thanks,

The patch is marked as:
Fixes: 5d41ce29e ("net: icmp6_send should use dst dev to determine L3
domain")

and that is only in 4.9. So there seems to be a little point backporting
to older kernels.

thanks,

it is water under the bridge now, but I started this thread because I 
noticed that some distributions are adding this to their own 4.8 kernels

Which actually makes sense now, given 5d41ce29e *was* backported to 4.8.
