I see no good reason to keep both rtl8169_reinit_task and rtl8169_reset_task:
- rtl8169_reinit_task adds a software failure point which does relate to
any hardware state
- they handle hardware the same. Remember that rtl8169_reinit_task was
introduced in the 8169 only era to handle PCI errors way before the 8168
asked for pll and firmware ops and compare :
