Subject: nuport-mac: check netif_receive_skb() return value
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8765e49fbeb61447a01003a92ab54ce883a88389;p=openwrt%2Fstaging%2Fyousong.git

nuport-mac: check netif_receive_skb() return value

We did not reassign status to netif_receive_skb() return value, we thus
almost always incremented the dropped counter because the descriptor status
value never matches the NET_RX_DROP.
