We're not after any "fall-through" behavior here. Replace the constructs with ones understood by all conforming shells, including older bash (problem observed with 3.1.51(1)). Fixes:b51715f02b("tools/hotplug/Linux: remove code duplication in vif-bridge") Fixes:3683290fc0("tools/hotplug: only attempt to call 'ip route' if there is valid command") Signed-off-by: Jan Beulich <jbeulich@suse.com> Reviewed-by: Paul Durrant <paul@xen.org> Reviewed-by: Bertrand Marquis <bertrand.marquis@arm.com> Acked-by: Wei Liu <wl@xen.org>
