http://p4web.freebsd.org/@@1202587?ac=10 Change 1202587 by jmg@jmg_carbon2 on 2014/11/07 00:40:50 add a method to map a device name to it's crid... This will allow us to specify which device to test... It'd be nice in the future to query and test all of the devices that are in the system, though as each one will support a different set of features, it'll be complicated to test and make sure we know they are correct..
