[OpenWrt-Devel] [PATCH 5/5] net: ethernet: mediatek: enhance with avoiding superfluous assignment inside mtk_get_ethtool_stats

[Rosen Penev]

From: Sean Wang <sean.wang at mediatek.com>

data_src is unchanged inside the loop, so this patch moves
the assignment to outside the loop to avoid unnecessarily
assignment
