The ETF input should be connected to the funnel output, and the ETF
output should be connected to the replicator input. The labels are wrong
and these got swapped:

Warning (graph_endpoint): /soc/funnel at 821000/ports/port at 8/endpoint: graph connection to node '/soc/etf at 825000/ports/port at 1/endpoint' is not bidirectional
Warning (graph_endpoint): /soc/replicator at 824000/ports/port at 2/endpoint: graph connection to node '/soc/etf at 825000/ports/port at 0/endpoint' is not bidirectional

Ping. Still seeing warnings in -next for these.

 Hi Rob,

 I no longer have access to this hardware and documentation.
 I am sure that Mathieu and friends will take care for verification
 of this patch :-)

The code triggers on the "slave-mode" property rather than the labels,
so this patch has no effect on how a path is established.  I've tested
this on a 410c and things look good.
