Thanks for reviewing it!
I have the impression that last parameter num value should be larger
than the attribute num value in 2nd parameter (TC_POLICE_RATE64 in this
case). This is the reason I changed the last parameter value to
__TCA_POLICE_MAX after I moved the new attributes after TC_POLICE_PAD in
pkt_cls.h header.

I rebuilt the kernel module act_police.ko by using TC_POLICE_PAD in the
4 parameter as before, I am able to set > 32bit rate and peakrate value
in tc command. It also works properly.

If the rest of community thinks I should keep using TC_POLICE_PAD in the
4th parameter too, I can change it to TC_POLICE_PAD in the next version.

Thanks!
