[PATCH net-next] e1000e: Be drop monitor friendly

From: Florian Fainelli
Date: Thu Aug 24 2017 - 21:37:06 EST


e1000_put_txbuf() cleans up the successfully transmitted TX packets,
e1000e_tx_hwtstamp_work() also does the successfully completes the
timestamped TX packets, e1000_clean_rx_ring() cleans up the RX ring and
e1000_remove() cleans up the timestampted packets. None of these
functions should be reporting dropped packets, so make them use
dev_consume_skb*() to be drop monitor friendly.
