Subject: [PATCH net-next 0/4] r8169: improve memory barriers

This series includes improvements for (too heavy) memory barriers.
Tested on x86-64 with RTL8168g chip version.

Heiner Kallweit (4):
  r8169: use smp_store_mb in rtl_tx
  r8169: change wmb to dma-wmb in rtl8169_start_xmit
  r8169: replace dma_rmb with READ_ONCE in rtl_rx
  r8169: use WRITE_ONCE instead of dma_wmb in rtl8169_mark_to_asic
