>Description:
In 6.2-STABLE (16/02/2007)

Tested with Dlink DWL-G510 rev C2 ( MAC/BPP RT2561C, RF RT2527 )
and with Ovislink Evo-W54PCI v.2 ( RT2561S ) PCI Cards 

After compiling and loading if_ral.ko module, the card appears correctly
into /var/log/messages and ifconfig but doesn't work at all when trying
to associate.

When trying to scan AP ( ifconfig ral0 scan ) BSSID, CHAN RATE S:N INT
and CAPS infos seems correct but NOT the SSID ( always SSID : 0 )

When trying to associate, status is still at "no carrier"


In 7.0-CURRENT :

All seems to work ( both scanning and association ) but _sometimes_ the
card disassociate itself, and it's impossible to reassociate until reboot.


On OpenBSD-4.1 :

All works _perfectly_


Output of dmesg :

ral0: MAC/BBP RT2561C, RF RT2527
ral0: Ethernet address: 00:19:5b:23:10:88
ral0: [GIANT-LOCKED]
>How-To-Repeat:
Just insert a RT2561* chipset into a fresh 6.2-STABLE install and try
to load if_ral (as module or into the kernel)

 Hi again,
 
 I've made additional debug informations, and with the following command
 I can _sometimes_ see my AP (ssid : myssid)
 
 # while :; do ifconfig ral0 scan; done | grep myssid
 myssid        00:06:f4:f6:ae:11   10   11M 114:0   100 EPS
 
 I've tried to set the debug mode and seen what happens :
 
 when "myssid" is detected :

 Hi,
 
 I just want to confirm this bug. I tried to get it to work with a clean
 6.2-stable snapshot. The correct module is loaded at startup, but
 scanning for networks fails (no error, it just doesn't show the networks
 in range).
 
 System:
 FreeBSD 6.2-STABLE-200703 #0: Tue Mar  6 22:06:57 UTC 2007
     root@dessler.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC
 
 Dmesg:
 ral0: <Ralink Technology RT2561> mem 0xcfff0000-0xcfff7fff irq 16 at device 12.0 on pci0
 ral0: MAC/BBP RT2561C, RF RT2527
 ral0: Ethernet address: 00:80:5a:4d:55:3a
 
 Ifconfig:
