 The Linux driver will allocate an ethernet device for each of the available vlans.
 Per default the driver will setup up the matrix such that each port has its own vlan and the cpu port is part off every vlan.

 ADM5120 switch hardware descriptor has 25-bit dma address field. So dma-addressible only 32Mb. But in MIPS Linux kernel dma-addressible all memory. So if you have memory more than 32Mb, driver would not works properly.
 And sometimes in switch drivers DMA mask is incorrect: 0xffffff instead 0x1ffffff (look in driver header files).
-If you set DMA mask in '''struct device''' of your switch device, then switch will work with any memory amount.

 However, AMiLDA Linux's kernel has this driver backported from 2.6, and so the admswconfig tool can be used perfectly.

 It has up to 6 external ports (5 on the SQFP package, the BGA package has an extra MII port).
 Also there is a special 'CPU' port which is used to send the packages to and from the CPU.
