Subject: [PATCH 4/5] netfilter: nf_flow_table: clear skb tstamp before xmit
Date: Fri, 30 Aug 2019 14:07:03 +0200 [thread overview]
Message-ID: <20190830120704.6147-5-pablo@netfilter.org> (raw)
In-Reply-To: <20190830120704.6147-1-pablo@netfilter.org>
From: Florian Westphal <fw@strlen.de>
If 'fq' qdisc is used and a program has requested timestamps,
skb->tstamp needs to be cleared, else fq will treat these as
'transmit time'.
