+Subject: [PATCH] remove dhclient-script bash dependency
+
+Take the dash compatible IPv6 link-local address test from the Debian
+version of dhclient-script.
+
+Note that although "echo -e" in the OE version of dhclient-script is
+technically bash specific too, it is supported by Busybox echo when
+Busybox is configured with CONFIG_FEATURE_FANCY_ECHO enabled (which
+is the default in the OE Busybox defconfig) therefore leave as-is.
+
+Upstream-Status: Inappropriate [OE specific]
+
