Subject: [PATCH net-next 0/4] r8169: remove fiddling with the PCIe max read
 request size

The attempt to improve performance by changing the PCIe max read request
size was added in the vendor driver more than 10 years back and copied
to r8169 driver. In the vendor driver this has been removed long ago.
Obviously it had no effect, also in my tests I didn't see any
difference. Typically the max payload size is less than 512 bytes
anyway, and the PCI core takes care that the maximum supported value
is set. So let's remove fiddling with PCIe max read request size from
r8169 too. This change allows to simplify the driver in the subsequent
three patches of this series.

Heiner Kallweit (4):
  r8169: remove fiddling with the PCIe max read request size
  r8169: simplify setting PCI_EXP_DEVCTL_NOSNOOP_EN
  r8169: remove rtl_hw_start_8168dp
  r8169: remove rtl_hw_start_8168bef
