[BusyBox 0000980]: patch to avoid "broadcast +" syntax

[Roberto A. Foglietta]

Hi to all,

 at least for me the bugfix n.980 and related patch feedback is closed

 http://bugs.busybox.net/view.php?id=980#bugnotes

busybox-1.2.2.1-ifconfig_3.patch: this is the last patch and the only
one I think it is enought correct to be included in busybox.

Problems fixed since the version 1.1.3 patch:

 1) double *++argv check to avoid to check argv[argc+1] ?= NULL
 2) added an #ifdef in the 3-cases-if to reduce the size with no
broadcast cfg opt

 I hope it will be enought to allow this patch enter in busybox.


 Cheers,
