Few questions about the wireless stack
Hi,
I am trying to understand the relationship between wireless interfaces (wlan0, mon0,..) and wireless driver.
The most important question I am after, is what types of interfaces I can
run simultaneously? (I know that I can run station and monitor, but what are other combinations ?)
I noticed that in monitor mode iwl3945 appends so called 'radiotap' header to received packets, but it seems that mac80211 strips this header, and appends its own,
for monitor interfaces, if so, then why to append it?
And lastly, when you expect AP code to be released?
Best regards,
Maxim Levitsky

I would be glad to hear about this, I have absolutely no free time to dig that out.

Last i can remember about the subject was Tomas
some months ago.
iirc the statement was something similar to:
- 3945 is a mini PCIe card, and hence not deployed in embedded? devices, therefore master mode support isn't planned for 3945
- patches are welcome

What do we need from the hardware to enable master mode?
I think that the best solution is to unite 3945 and rest of the driver code, since it is all the same.
You say that 4965 is pci express. does that mean I can buy a standalone version of it?

FWIW, the PC Engines Alix.6* boards has or will include a miniPCI express slot.
As someone building stuff from these and similar boards, I appreciate having options.

3945 runs on mini PCIe ___wx__ bus not regular miniPCIe. There is no real problem that 3945 will run in AP/master mode I just don't think than anyone will make embedded device from it.

Okay. I have no idea what difference there is between wx bus and regular mini PCI express.

wx runs of 1/3 of frequency of regular pcie bus. It was one time adventure and further product uses regular pcie bus. Tomas
