[PATCH] net (tg3): Fix failure to enable WoL by default when possible (rev. 2)

[Rafael J. Wysocki]

Subject: net (tg3): Fix failure to enable WoL by default when possible (rev. 2)

tg3 is supposed to enable WoL by default on adapters which support
that, but it fails to do so unless the adapter's
/sys/devices/.../power/wakeup file contains 'enabled' during the
initialization of the adapter.  Fix that by making tg3 update the
device's 'should_wakeup' bit automatically whenever WoL should be
enabled by default.
