[PATCH] wifi-test: add initial simple test scripts

[PATCH] wifi-test: add initial simple test scripts

[Luis R. Rodriguez]

The wifi-test project currently deals only with a robust
test setup and requires access to an AP with a CLI like
the Cisco APs. For simpler environments such as an end
user we can work on simpler scripts and tests cases.

Lets start this off with some initial basic scripts to
start an AP with different encryption possible settings
and a client to connect to that AP. To start off with
we use wext as that has been tested previously. We'll
replace this with iw commands ASAP.

I'm submitting these as-is from some old stuff I had which I had
tested with MadWifi. Eventually I'll test with ath9k and 11n, etc.
Feel free to send patches :)

+Simple testing utilities are only starting to being developed, for those

RE: [PATCH] wifi-test: add initial simple test scripts

[Zheng, Jeff]

Thanks Luis, I have checked it in.

Do these scripts (client and AP) run on the same machine? If yes, will
packets be sent/received through air, or through mac80211 as bridge?

I have a sample case with hwsim (hwsim.sh), which simulates two wlan
interface (one for client and one for hostapd). It can be used for
testing mac80211.

Bests
Jeff
