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.
--------------------
commit 63c3a66fe6c827a731dcbdee181158b295626f83

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.
