ASF strategy should propagate NACK if all nexthops are NACKed
So other nodes would rank those faces lower.

Additionally, after probems on the testbed in the week of October 9, 2017, some more issues arose:
The ASF strategy reacts identically to all kinds of NACKS, currently treating them as timeouts. This causes ASF to treat that nexthop as "not very suitable" for retrieving data. However, this isn't always true. The ASF strategy should understand the differences between NACKs, and treat them accordingly.
