[OpenWrt-Devel] [PATCH][ar71xx] Mikrotik Routerboard RB2011 switch fix

[Fernando Frediani]

Hello George.
No, unfortunatelly it doesn't. I was trying to get a more objective 
reply from perhaps whoever built and maintains this router profile in 
order to understand and compare when using original firmware and OpenWrt 
customized to it. All around the performance X feature list.
As the wiki doesn't mention that I asked it here.

Thanks
Fernando
