Subject: ipv6: tcp: dont drop packet but consume it
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ab185d7b2551e9b8d946a657ddccd86d192bebd1;p=linux-beck.git

ipv6: tcp: dont drop packet but consume it

When we need to clone skb, we dont drop a packet.
Call consume_skb() to not confuse dropwatch.
