+Subject: igc: Remove _I_PHY_ID checking
+
+i225 devices have only one PHY vendor. There is no point checking
+_I_PHY_ID during the link establishment and auto-negotiation process.
+This patch comes to clean up these pointless checkings.

+Subject: igc: Remove phy->type checking
+
+i225 devices have only one phy->type: copper. There is no point checking
+phy->type during the igc_has_link method from the watchdog that
+invoked every 2 seconds.
+This patch comes to clean up these pointless checkings.
