Subject: [PATCH v2 net-2.6] jme: Support WoL after shutdown
From: Guo-Fu Tseng <cooldavid@...ldavid.org>
Adding shutdown function that setup wake if wol is enabled.
Add jme_phy_on in jme_set_100m_half in case it is shutting down
or suspending when interface is down(phy_off by default).
v2 updates:
Removed CONFIG_PM ifdef for jme_set_100m_half and jme_wait_link.
It would be nice if it can be applied to net-2.6 along with other patches
sent few days ago. If it is not appropriate, please ignore the net-2.6
request, and apply it to net-next-2.6 as previous patch. :)
