The patch below helps when using VETH and bridge(s) This makes sure that the pkt timestamp is properly (re)calculated on receiving the packet on the peer veth device. I'm sure this patch is white-space damaged. If this looks useful, I'll generate a clean patch and send as attachment. Signed-off-by: Ben Greear<greearb@candelatech.com> Thanks, Ben
