[klibc] Request: Infiniband Support in ipconfig

When attempting to boot a system using Infiniband interfaces, ipconfig does not recognize Infiniband NICs as having valid MAC addresses, so they are silently ignored.  As I would like to be able to netboot using Infiniband, I have patched ipconfig to support Infiniband interfaces.

Fortunately, it's a pretty simple and straightforward patch.  Below is the patch for your consideration.

 		dev->hwlen = 0;
+        case ARPHRD_INFINIBAND:
+                dev->hwlen = 20;
+                break;
 		return -1;

As you can see, it simply returns the proper length of the IB interface's MAC address.
