route use?

I've recently noticed that the use column in /proc/net/route doesn't seem
to update as often as it did in 1.2.x. i.e.

Kernel routing table
Destination Gateway Genmask Flags MSS Window Use Iface
localnet * 255.255.255.0 U 1500 0 38 eth0
loopback * 255.0.0.0 U 3584 0 2 lo
default fdt-gw.fdt.net * UG 1500 0 1 eth0

This is from a box running 2.0.0. I've been telnetted in for 16 hours
testing and compiling things. It's sent alot more than 38 packets over
the localnet route.

Kernel routing table
Destination Gateway Genmask Flags MSS Window Use Iface
localnet * 255.255.255.0 U 1500 0 214 eth0
loopback * 255.0.0.0 U 1500 0 24 lo
default fdt-gw.fdt.net * UG 1500 0 7881 eth0

This is from an IRC server running 1.3.72, up for 11 days. It's
averaging about 60MB of traffic in each direction per day.

With 1.2.13, I see numbers like this:
localnet * 255.255.255.0 U 1436 0 48925379 eth0
loopback * 255.0.0.0 U 1936 0 2616277 lo
default fdt-gw.fdt.net * UG 1436 0 11585054 eth0

Have the units in "Use" changed or something?
