X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=0c509a6c9393b27a8c5a01acd4a72616206cfc24;p=openwrt%2Fstaging%2Fblogic.git 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.
