Inclusion of fc791b6335152c5278dc4a4991bcb2d329f806f9 ("IB/ipoib: move back IB LL address into the hard header")

[Nikolay Borisov]

Hello,

I'd like to ask the patch in the subject to be merged into current
stable trees starting from 4.4. The fixes tag of the patch cites a
commit which was introduced into 4.5, however the problem exists even on
4.4 kernel. For more information you can check:
https://bugzilla.kernel.org/show_bug.cgi?id=111921

Regards,
Nikolay

Any reason you didn't cc: the developers of that patch and the
maintainers of the subsystem so that they can answer this question?

thanks,

Mainly because I didn't know I had to, hopefully it's better now :)

The patch should be safe to apply to earlier kernels if they also show
the problem.  However, I know that context diffs will cause the patch
from applying long before you reach the patch that introduced this
issue:

stash LL addresses

I can confirm that this patch fixes issue for me on 4.4.44 kernel.
