Hi Jason, This was a *huge* help to get this response from you, thanks a bunch for that. I'd love to poke GregKG's staging tree and the mac80211 driver for the bcm4329. I did some searching for the staging tree, and the only address I could find was: git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git But whenever I try to clone it, it just hangs up on me. "fatal: The remote end hung up unexpectedly" ... is there another location that I'm not finding? I can definitely give cyanogenmod a shot, I had it running on my old G1 at one point. Let me toss it on my Incredible and see where we can go. I actually tried to go the wl1271 on my Droid1 first with this code: http://android.git.kernel.org/?p=platform/hardware/ti/wlan.git;a=tree I am able to read the 802.11 header in the kernel module before it gets translated to an Ethernet frame. That was a great step towards what I wanted, I just needed to then kick it in to promiscuous mode. The mode is disabled, but I figured I could reconfigure the RX filter. I changed the RX filter to disable BSSID filtering, but I was still only getting packets destined to my MAC. But, then I found this comment which appears to state that the firmware sets the local MAC address filter (plus broadcast traffic): http://android.git.kernel.org/?p=platform/hardware/ti/wlan.git;a=blob;f=wl1271/TWD/Ctrl/CmdBldCmd.c#l147 So it seems like the firmware is preventing the driver from removing the BSSID filter on the wl1271. But, as you mentioned the N900 was able to kick it in to promiscuous mode which must be changing this filter. Is it using a different firmware? But, I'm going to explore the in-kernel driver for this as you mentioned. I will start poking around that. Thanks again, I really appreciate it. - George On Mon, Mar 7, 2011 at 9:01 AM, Jason <linuxdriverproject@xxxxxxxxxxxxxx> wrote: > On Sun, Mar 06, 2011 at 11:11:48PM -0500, George Nychis wrote: >> Hi all, >> >> I was really hoping to be able to access 802.11 headers of received >> packets on a BCM4329 chip embedded on my HTC Incredible.
