From 7e49d6165e4a6c5df7f32c16976b33bfd830b92c Mon Sep 17 00:00:00 2001 From: Don Skidmore Date: Tue, 9 Jun 2015 17:48:54 -0700 Subject: [PATCH] ixgbe: Set lan_id before using I2C We need to call the set_lan_id before accessing I2C and this wasn't being done so this patch corrects that. Likewise we do the same for QSFP just to be consistent. In the X550 case this is even more important as with out it the mux is not controlled properly.
