ath problem with 6.0-BETA5

[Daniel O'Connor]

Hi,
I have a 6.0 test box here with an Atheros based card in it..
ath_hal: 0.9.14.9 (AR5210, AR5211, AR5212, RF5111, RF5112, RF2413)
ath0: <Atheros 5212> mem 0xdc000000-0xdc00ffff irq 11 at device 9.0 on pci0
ath0: Ethernet address: 00:00:8c:00:72:e0
ath0: mac 7.9 phy 4.5 radio 5.6

I am using it to run a wireless link to a 5.4 box running openvpn over an 
Atheros based 108Mbit AP.

The problem I am having is that after several hours (eg 12-24+) the atheros 
card will stop sending packets (or maybe receiving them) and I end up with 
ping complaining that the host is down (as well as openvpn). I can fix the 
link by doing ifconfig ath0 down ; ifconfig ath0 up.

The link is 'bare' - ie no WEP or WPA, it only transmits OpenVPN's UDP packets 
in the clear.

current# ifconfig ath0
ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 10.0.2.1 netmask 0xff000000 broadcast 10.255.255.255
        ether 00:00:8c:00:72:e0
        media: IEEE 802.11 Wireless Ethernet autoselect (OFDM/54Mbps)
        status: associated
        ssid APOCAE6B channel 6 bssid 00:00:8c:00:79:5b
        authmode OPEN privacy OFF txpowmax 32 protmode CTS bintval 100

I am dumb and just fixed the link before running some tests but next time it 
happens I will run tcpdump and see if any traffic is being received.

I have also seen 'ifconfig ath0 scan' cause the interface to break (ie not 
tx/rx packets) and a down/up fixed it, but it was not repeatable nor am I 
sure it is related to this problem.
