From 0c509a6c9393b27a8c5a01acd4a72616206cfc24 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Thu, 29 Oct 2009 14:18:21 +0000 Subject: [PATCH] net: Allow devices to specify a device specific sysfs group. This isn't beautifully abstracted, but it is simple, simplifies uses and so far is only needed for the bonding driver. Signed-off-by: Eric W. Biederman Signed-off-by: David S.
