[PATCH 1/2] gianfar: Deal with link state changes during GFAR_RESETTING dev state

2017-02-13 Thread Thomas Graziadei
From: Thomas Graziadei The link state is not correctly set in the case that the network driver is reconfigured while the link state changes. The phy informs the gianfar driver, but gfar_update_link_state just exits and therefore looses the change event. The network driver remains in the old

[PATCH 2/2] gianfar: Use the same initial values as the phy layer

From: Thomas Graziadei The user notices the problem in a raw and real time drift, calling clock_gettime with CLOCK_REALTIME / CLOCK_MONOTONIC_RAW on a system with no ntp correction taking place (no ntpd or ptp stuff running). The problem is, that old_vsyscall_fixup adds an extra 1ns even though
