Chunhao Lin af0bedfbcb r8169: fix dmar pte write access is not set error
[ Upstream commit bb41c13c05 ]

When close device, if wol is enabled, rx will be enabled. When open
device it will cause rx packet to be dma to the wrong memory address
after pci_set_master() and system log will show blow messages.

DMAR: DRHD: handling fault status reg 3
DMAR: [DMA Write] Request device [02:00.0] PASID ffffffff fault addr
ffdd4000 [fault reason 05] PTE Write access is not set

In this patch, driver disable tx/rx when close device. If wol is
enabled, only enable rx filter and disable rxdv_gate(if support) to
let hardware only receive packet to fifo but not to dma it.
