Subject: veth: Zero timestamp in xmit path.
X-Git-Tag: firefly_0821_release~12983^2~572
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=27a242e92f77c955433ce0347533f401ecdcd0f3;p=firefly-linux-kernel-4.4.55.git

veth: Zero timestamp in xmit path.

This patch zero's the timestamp before handing the packet to
the peer interface.  This lets the peer recalculate the rx timestamp
if it cares about timestamps.
