From 01b3fd5ac97caffb8e5d5bd85086da33db3b361f Mon Sep 17 00:00:00 2001 From: Baruch Siach Date: Tue, 4 Dec 2018 16:03:52 +0200 Subject: net: mvpp2: fix detection of 10G SFP modules The mvpp2_phylink_validate() relies on the interface field of phylink_link_state to determine valid link modes. However, when called from phylink_sfp_module_insert() this field in not initialized. The default switch case then excludes 10G link modes. This allows 10G SFP modules that are detected correctly to be configured at max rate of 2.5G. Catch the uninitialized PHY mode case, and allow 10G rates.
