Xilinx LocalLink Tri-Mode Ether MAC driver can be used by Xilinx Microblaze or Xilinx ppc405/440 in SDMA and FIFO mode. DCR or XPS bus can be used. The driver uses and requires MII and PHYLIB. CP: 4 warnings: 'Use of volatile is usually wrong' I won't fix this, because it depends on the network driver subsystem.
