[PATCH] ver_linux: wireless-tools.patch

From: Alexander Kapshuk
Date: Thu Oct 01 2015 - 14:42:19 EST


Using 'awk' here is a bit of an overkill. Should the output of 'iwconfig
--version' vary on another disto, or change overtime, it may no longer
be available in field 4, as relied on by the current implementation.

I believe 'sed' offers greater flexibility here in terms of processing
varying output as well as being more light-weight.


Tested on:
Arch Linux
openSuSE 13.2
