[PATCH] Add filter option to test/test-discovery

From: Anderson Lizardo <hidden>
Date: 2011-02-25 21:38:31
Subsystem: the rest · Maintainer: Linus Torvalds

Add a new --filter option, which can be used to only show discovery
results which satisfy a given (Python) expression. This expression can
use any property of a discovered device. Example:

test-discovery -f "Name == 'BlueZ'"
test-discovery --filter="LegacyPairing == 1"

This option is useful for showing only devices which we are interested
on, e.g. LE devices (once we have a property to identify them).
