From 151dca093597031aa940271f31ab63a30a78240a Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Thu, 30 May 2013 17:38:28 +0000 Subject: [PATCH] ar71xx: make the SFP port usable on RB2011*S boards The port 6 of the switch is connected to the SFP cage on the RB2011*S boards. Add a helper function to correctly initialize the switch configuration data on those boards to make the SFP port usable.
