This patch cleans up the code path which is mostly dead to begin with. - add device IDs check in ixgbe_device_supports_autoneg_fc(). - ixgbe_fc_autoneg_fiber_x550em_a() is now used only to pass the user settings to ixgbe_fc_enable_generic(). - make sure that start_hw does not fail when setup_fc is not implemented. - small fix in the debug message when ixgbe_device_supports_autoneg_fc() returns false.
