Subject: [netdrvr] forcedeth: reorder suspend/resume code
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=25d90810ff49d2a63475776f24c74c6bb49b045f;p=openwrt%2Fstaging%2Fblogic.git

[netdrvr] forcedeth: reorder suspend/resume code

Match the suspend/resume code ordering in e100/e1000e more closely.
For example the configuration space should be saved on suspend even for
devices that are not up.
