The attached patch for 8.0-STABLE enables multicast key search capability for devices which support it in the ath(4) driver. This fixes the problem of corrupted multicast traffic when more than one hostap VAP is configured on a device. You can tell if your ath(4) device supports this capability by looking at the kernel log for "kernel: ath0: using multicast key search" as the device is attached. Please test if you are using the ath(4) driver. I only have AR5212 chipsets to test with and would like to see this included in 8.0-STABLE and 9.
