Let the user know what errors are experienced on received packets.

Browse Source 
I spent the better part of a day trying to figure out why my
experiment didn't work the way I expected, only to find out that
the router was dropping huge numbers of packets because of PCI bus
priblems.  This does not fix the bug that errors are counted as
input packets because my patch doesn't apply cleanly.
