3.16.47-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: YueHaibing <yuehaibing@xxxxxxxxxx>
commit 37a7fdf2892be124545ddaf99b85de576121476c upstream.
Now tg3 NIC's stats will be cleared after ifdown/ifup. bond_get_stats traverse
its salves to get statistics,cumulative the increment.If a tg3 NIC is added to
bonding as a slave,ifdown/ifup will cause bonding's stats become tremendous value
(ex.1638.3 PiB) because of negative increment.
Fixes: 92feeabf3f67 ("tg3: Save stats across chip resets")
