Hi
Can it just move
skb->tstamp = ktime_set(0, 0);
into
skb_tstamp_tx(skb, &shhwtstamps);
if it always need to clear for HW tstamp setting.

Since 'tcfp_burst' with TICK factor, driver side always need to recover
it to the original value, this patch moves the generic calculation and
recover to the 'burst' original value before offloading to device driver.

Current police action must set 'rate' and 'burst'. 'mtu' parameter
set the max frame size and could be set alone without 'rate' and 'burst'
in some situation. Offloading to hardware for example, 'mtu' could limit
the flow max frame size.
Change the double quotes to single quotes in fprintf message to make it
more readable.
