[BusyBox] ifconfig and pointopoint

[Michael Smith]

Hi,

I noticed a problem with ifconfig in busybox 0.60.5. The matching code
seems to exist in busybox CVS as well, so I'll paste in the patch that
fixed it.

I was running:
 # ifconfig wan0 1.2.3.4 pointopoint 1.2.3.5 netmask 255.255.255.255

I was seeing the inet addr and P-t-P addr both being set to 1.2.3.5
(the pointopoint address).

wan0      Link encap:Point-Point Protocol
          inet addr:1.2.3.5  P-t-P:1.2.3.5  Mask:255.255.255.255
          UP POINTOPOINT RUNNING NOARP  MTU:1500  Metric:1
          ...

The patch below seems to fix it.

Mike
