[PATCH v4 3/8] netdev: store signal threshold in netdev object, not globally

[James Prestwood <prestwoj@gmail.com>]

This prepares for the ability to toggle between two signal
thresholds in netdev. Since each netdev may not need/want the
same threshold store it in the netdev object rather than globally.
