This patch optimizes the RX buffer management by using the page pool. The purpose for this change is to prepare for the following XDP support. The current driver uses one frame per page for easy management. Added __maybe_unused attribute to the following functions to avoid the compiling warning. Those functions will be removed by a separate patch once this page pool solution is accepted. - fec_enet_new_rxbdp - fec_enet_copybreak The following are the comparing result between page pool implementation and the original implementation (non page pool). --- small packet (64 bytes) testing are almost the same --- no matter what the implementation is --- on both i.MX8 and i.MX6SX platforms. shenwei@5810:~/pktgen$ iperf -c 10.81.16.245 -w 2m -i 1 -l 64 ------------------------------------------------------------ Client connecting to 10.81.16.245, TCP port 5001 TCP window size:

The MPC5200's FEC can connect to the Ethernet either with
|
|
an external MII PHY chip or 10 Mbps 7-wire interface
|
|
(Motorola? industry standard).
|
|
If your board uses an external PHY connected to FEC, enable this.
|
|
If not sure, enable.

If compiled as module, it will be called fec_mpc52xx_phy.
