[OpenWrt-Devel] [PATCH][ar71xx] Routerboard 951G Switch Fix

I don't think this is related to the kernel. This issue was also in
Barrier Breaker ( 3.10 ). The CPU was changed in the Routerboard
951G's from an ar9344 rev. 2 to a ar9344 rev. 3. I am wondering if the
processor revision change had anything to do with it. Here is the
OpenWRT Bug confirming the issue was in Barrier Breaker (
https://dev.openwrt.org/ticket/18433#comment:6 ). Hope this bit of
information helps.
