Subject[PATCH] tg3: Fix failure to enable WoL by default when possible
Date
From: Rafael J. Wysocki <rjw@sisk.pl>

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 use
device_set_wakeup_enable() to enable wakeup automatically whenever
WoL should be enabled by default.
