ath problem w/ WPA2

[Slawa Olhovchenkov]

ath0: <Atheros 5212> mem 0x88000000-0x8800ffff irq 16 at device 0.0 on cardbus0
ath0: [ITHREAD]
ath0: AR2413 mac 7.9 RF2413 phy 4.5

After 1 hour stable working card lost all traffic.
This is time of EAP reauthentication period.

When using Intel card -- all works OK.

With very old kernel (~ 1 year old) all works OK.

I can't test intermediate kernel -- on this kernels
cardbus port don't powered correctly.

Last update to -current -- now.
