bloated vs debloated wireless test (iwllagn <-> wndr5700)

[Dave Täht]

I did a little testing of my quick n' dirty wireless patch for the ath9k
on what I have.

The two devices are:

a netgear wndr 5700 running openwrt
a laptop with the iwllagn driver

Connected at 36Mbit, going from the (De-bloated)wndr 5700, using iperf
to saturate the link, ping times ranged from ~2ms to ~4ms.

In the opposite (bloated) direction from the lagn, they peaked at about 140ms.

Under contention (10 streams), I experienced about 4% packet loss on ping.
(I've never been so happy to see packet loss in my life)

The ath9k patch for openwrt - while still far from ideal - is here:

My test rig - which uses the babel protocol to make it easier to move
between routers and routed devices - is described (partially) here:
