Is there no way to tell Linux to arrange that packets be delivered to

at least, provide some mechanism to allow libpcap to sort the packets 
in time stamp order before it delivers them?

That thread was 8 years ago, and a couple replies down, Alan Cox said: 
"You should never need it. Ethernet, hubs, switches, routers, internet 
backbones etc will all cause packet re-ordering. You should also expect 
the percentage of re-ordered frames on the net to rise and rise." *sigh*

The first reply says to use "IRQ Affinity," which appears to allow you 
to specify which CPU(s) are allowed to process certain interrupt 
requests.
