Subject: [PATCH v2 net-next 2/2] net: usb: r8152: Fix rx_bytes/tx_bytes to include FCS
Date: Tue, 23 May 2017 23:10:58 +0200 [thread overview]
Message-ID: <1495573858-32346-3-git-send-email-andrew@lunn.ch> (raw)
In-Reply-To: <1495573858-32346-1-git-send-email-andrew@lunn.ch>
The statistics counters rx_bytes and tx_bytes don't include the
Ethernet Frame Check Sequence. Fix the rx_bytes/tx_bytes counters to
include the FCS, and include the received FCS in the skb.
