Not really a backports question so adding linux-wireless

Does anyone know if there is any documentation on this or a URL that I
could reference before I attempt?
I guess the "private WiFi ioctl's" you are referring to are the ones
used in Android wpa_supplicant driver_cmd lib? There is no real
cookbook on how to add nl80211 commands (maybe I am wrong here), but
there are sufficient patches to be found in the linux-wireless
archive. A recent one about key management offload adds a couple of
commands and attributes which may give an idea what is needed:

Obviously, you need to modify the "couple of drivers" to deal with
the nl80211 netlink commands.
We had same requirement in our driver, we have patched the iw to send
custom commands specific to our hardware and used NL80211_CMD_TESTMODE
to process and send it to driver.

Yeah thanks a lot, I could use NL80211_CMD_TESTMODE, I'll have to check
that out. I was also thinking about using NL80211_CMD_VENDOR. These
IOCTL's are not and will not be used by wpa_supplicant (but I will check
out the URL you sent), they are just some custom commands we use with
several chipsets.
If you are using recent kernel or backports package, I would say go for
the vendor command. It is quite similar to TESTMODE except that it is
always enabled, ie. not depending on kernel config.
However, if the custom commands would add functionality that might be
interesting to linux-wireless drivers in general you may consider adding
them as nl80211 commands.

Arend
