There are two ways to do this.  One is through the system page which is created in the init_hwinfo.c file in the BSP.  
This places information about each interface in a location in memory (the system page) that the driver can access (when 
you give it the syspage option).  This is the "recommended" way of doing it.

You can also do the equivalent with ifconfig.  The 8641 uses the devnp-mpc85xx driver (if you're on 6.4.0 with io-pkt). 
 It will create tsec0, tsec1, tsec2 and tsec3 interfaces for you.  The enx naming convention is used when you use the 
old-style io-net driver (devn-mpc85xx.so).

I'd recommend that you take a look through the networking wiki

for more information.

Subject: Newbie - how to create multiple Ethernet ports
 
So my development is based on BSP for MPC8641D board that support 4 eTSECs.  I've seen examples on setting up 1 instance
 of Ethernet using io-net.  But how do I create multiple instances of it, each associates with a specific unique MAC 
address for a specific TSECn (and perhaps with some other slightly different configuration)?

I've seen in some posts using ifconfig <interface>.  Does <interface> naming have any bearing with device naming (e.g. 
TSEC0, vs. en0 etc)?

I've also seen in devn-mpc85xx.use file the specification of syspage on the io-net script line.  What (e.g. which field)
 would you use to specify anything presumably hardware specific for each instance of Ethernet Controller?

Some example scripts for creating multiple ports would be greatly appreciated.

Thanks,
Raymond
