net: lan743x: Add set RFE read fifo threshold for PCI1x1x chips
[ Upstream commit e4a5898 ] PCI11x1x Rev B0 devices might drop packets when receiving back to back frames at 2.5G link speed. Change the B0 Rev device's Receive filtering Engine FIFO threshold parameter from its hardware default of 4 to 3 dwords to prevent the problem. Rev C0 and later hardware already defaults to 3 dwords.
