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.
