wireless network "supported" card roundup: 1 of 3 works

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

I've just tried three different "supported" wireless network cards.

ral0 at pci2 dev 2 function 0: Ralink Technologies RT2561S 802.11b/g (rev. 0x00)
ral0: interrupting at ioapic1 pin 17
ral0: 802.11 address xx:xx:xx:xx:xx:xx
ral0: MAC/BBP RT2561C, RF RT2527
ral0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
ral0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps
24Mbps 36Mbps 48Mbps 54Mbps

I could configure the network, it automatically found the correct SSID
and channel. The "TX rate (actual speed)" in wiconfig dropped and
dropped until it was at "1"; I couldn't ping the access point:
PING ap (192.168.0.1): 56 data bytes
ping: sendto: Host is down
...

Next one up, atu0:
# dmesg | tail
atu0 at uhub8 port 6
atu0: Linksys WUSB11-V28, rev 1.10/1.00, addr 4
atu0: reattaching after firmware upload
# ifconfig atu0
ifconfig: SIOCGIFFLAGS atu0: Device not configured

This one seems to work fine:
rum0 at uhub8 port 6
rum0: Ralink 802.11 bg WLAN, rev 2.00/0.01, addr 4
rum0: MAC/BBP RT2573 (rev 0x2573a), RF RT2528, address xx:xx:xx:xx:xx:xx
rum0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
rum0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 
36Mbps 48Mbps 54Mbps
# ifconfig rum0

What would be useful information to put in a PR?
