ath0 messages spamming /var/log/messages

[John]

Hello list,

On an acer laptop I'm running 10.2 r292394. Wireless on this is seen
as Atheros AR9485 and it runs fine apart from it spamming
/var/log/messages with this:

Dec 29 10:12:07 acer kernel: Limiting closed port RST response from
210 to 200 packets/sec

Dec 29 10:13:01 acer kernel: ar9300_Stub_GetAntennaSwitch: called

Is there a tweak or something I can invoke to stop this from
happening? The on-board wifi is seen as:

ath0: <Atheros AR9485> mem 0xf0100000-0xf017ffff irq 17 at device 0.0
on pci2

Initial output from dmesg.boot shows this:

The wifi works fine apart from the chatty output.

thanks,
