X-Git-Tag: v4.11-rc1~124^2~293^2~1
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=922754a48a4e4b87ee6f5bf80e7463a82e124ab8;p=uclinux-h8%2Flinux.git

net: dsa: qca8k: use dsa_port's bridge pointer

Now that DSA exposes the bridge device pointer to which a port belongs,
use it when programming the port based VLANs and thus remove the cache.
