[PATCH] Require all interfaces to be up before using iscsistart -b

[Ross Lagerwall <ross.lagerwall-Sxgqhf6Nn4DQT0dZR+AlfA@public.gmane.org>]

If multiple targets are specified in the ibft, iscsistart will log into
all of them, possibly using multiple interfaces. Since iscsistart is run
indirectly from ifup, require that all interfaces are up before actually
logging into the targets.
