packet drop counters?

 Hi everyone,

I'm doing some traffic testing with the libertas driver on the OLPC.
I'm using olpc build 709 (which doesn't tell you the driver version,
I'll track that down).

I'm seeing some intermittant, but fairly large bursts of packet loss
when I run the tests.

For example, one scenario is I have 2 pairs of XOs.   Each pair has a
source and a sink.

When the sources are sending 1000 byte UDP packets at 600 packets per
second, I have seen up to 2000 packets dropped over a 5 second interval.
Most of the time it works well but once in a while I get these large
bursts of traffic loss.

Are there any counters, etc. I can retrieve from the driver to help
debug this?
