From: Sasha Neftin <sasha.neftin@xxxxxxxxx> commit 8eef5c3cea65f248c99cd9dcb3f84c6509b78162 upstream. This reverts commit 86167183a17e03ec77198897975e9fdfbd53cb0b. igc_ptp_init() needs to be called before igc_reset(), otherwise kernel crash could be observed. Following the corresponding discussion [1] and [2] revert this commit.
