I'm playing with the driver and mac80211 stack to get some ad-hoc-like
functionality. I am able to do a ping among two non-associated nodes,
but I get about 9 ping replys (i.e. 8 duplicates) for each ping

I found out the problem is that the frames are not being acked, so
they are retransmitted. I haven't found the code for retransmission
nor for ack generation, so I am not sure what do I need to do to make
the device generate acks.

At http://wireless.sipsolutions.net/en/users/Drivers/zd1211rw/mac80211Issues
I found:

"Johannes writes:

In zd1211, we start with hwaddr = dev->wiphy->perm_addr which isn't
correct either, for a pure monitor mode we want to start with a zero mac
addr to avoid acking packets. Also, zd1211rw will end up having a NULL
hwaddr when a monitor interface is added, most likely segfaulting in
zd_write_mac_addr then."

which leads me to think by default the node would issue acks...

Any help or explanation of how ack generation works for the device
would be greatly appreciated.
