Subject[PATCH 3.2 113/115] jme: Do not enable NIC WoL functions on S0
3.2.80-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Guo-Fu Tseng <cooldavid@cooldavid.org>

commit 0772a99b818079e628a1da122ac7ee023faed83e upstream.

Otherwise it might be back on resume right after going to suspend in
some hardware.
