Re: [PATCH] tg3: Fix failure to enable WoL by default when possible

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.

Applied, thanks Rafael.

Stephen, this patch is going to show up in net-2.6 and it will
generate a merge conflict with Joe Perches's commit in net-next-2.6
which converts tg3 to use a bitmap for the tp->tg3_flags* values.

    tg3: Convert u32 flag,flg2,flg3 uses to bitmap
--------------------

It should be easy to resolve, and you don't need to report this
to us when you hit it while building your -next tree, thanks :-)

I'll resolve it myself over the next day or two.
