Thanks a lot!

On top of your branch i tested with scaling 3 different test paths (also
tagged with different tags) and it looks good:

 node                                  tag          avg         peak
--------------------------------------------------------------------
slv_ebi_ch0                                      458824      1525000
  cpu0                                   3          922          911
  cpu0                                   2          902          901
  cpu0                                   1       457000      1525000

Apart from that, i ran memory throughput tests and they also confirm
that it's working as expected.

There will be a minor conflict with my branch when this is merged upstream,
so maybe we will need to report it or use an immutable tag/branch.

Thanks,
Georgi
