02:00.0 Network controller: Atheros Communications Inc. AR5008 Wireless Network
Adapter (rev 01)
Subsystem: Apple Computer Inc. Device 0087
Flags: bus master, fast devsel, latency 0, IRQ 17
Memory at b0100000 (64-bit, non-prefetchable) [size=64K]
Capabilities: <access denied>
Kernel driver in use: ath9k
Kernel modules: ath9k
Using jaunty with linux-backports-modules' ath9k:
ii linux-backports-modules-2.6.2 2.6.28-8.6 Ubuntu supplied
Linux modules for version 2.6.28 on x86/x86_64
ii linux-image-2.6.28-8-generic 2.6.28-8.22 Linux kernel
image for version 2.6.28 on x86/x86_64
Network tested on: 802.11g WPA2-PSK
When the wifi interface isn't in promiscuous mode, broadcast packets
aren't received. No errors reported, just no broadcast. This means that
one can make outgoing connections but can't reliably receive incoming
connections.
Turning on promiscuous mode results in these packets being received
again.
Steps to reproduce:
* Connect to a WiFi AP.
* Ping the network broadcast address from another machine (wired or wireless,
assuming the AP is bridging).
* Run tcpdump on the ath9k target machine, both with and without the "-p" flag.
