Subject: save the boot loader's vlan config before setting the failsafe config and restore... 
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fsvn-archive%2Farchive.git;a=commitdiff_plain;hb=f2fa597e6d7312c85cc212f604c279ffa00f8c16

save the boot loader's vlan config before setting the failsafe config and restore it just before running /sbin/init - necessary for wrt54g v1.1, which doesn't have vlan*ports variables
