You don't have to log each packet to do accounting.  If you create 1 iptables 
rule for each src address, you know how many packets and bytes that that src 
address transmitted.

iptables -A INPUT -s 192.168.1.0
iptables -A INPUT -s 192.168.1.1
iptables -A INPUT -s 192.168.1.2

iptables -L -v -n
Chain INPUT (policy DROP 47 packets, 5842 bytes)
 pkts bytes target     prot opt in     out     source   destination
    0     0            all  --  *      *       192.168.1.0          0.0.0.0/0
    0     0            all  --  *      *       192.168.1.1          0.0.0.0/0
    0     0            all  --  *      *       192.168.1.2          0.0.0.0/0
