From cfd8e12f42746df396ecbdf7a1d8e92e8e4dbb97 Mon Sep 17 00:00:00 2001 From: Ben Greear Date: Mon, 11 Oct 2010 10:28:59 -0700 Subject: [PATCH] wireless: Print wiphy name in sysfs. The index cannot be used to reliably reconstruct a phy name, so explicitly add the phy name to sysfs so that scripts can figure out the parent phy device for a particular wireless interface.
