From: Dave Jiang Date: Thu, 24 Sep 2015 20:03:05 +0000 (-0700) Subject: NTB: unify translation addresses X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8b782fab4da771c97a198f6cb496d124dace36fd;p=openwrt%2Fstaging%2Fblogic.git NTB: unify translation addresses There is no need for the upstream and downstream addresses to be different for the NTB configs. Go to using a single set of address. It is still possible to configure them differently using module parameter override however.
