compat-wireless use of iwlwifi driver in Android ics imx6

[michaelrobbelot]

Anyone,

I am trying to get the compat-wireless package to work with the imx6 Android BSP. I am able to get the mac80211, cfg80211, and compat drivers to load fine, but the iwlwifi driver refuses to load. I am getting error messages of the following form:

iwlwifi: disagrees about version of symbol ieee80211_stop_tx_ba_session

iwlwifi: Unknown symbol ieee80211_stop_tx_ba_session (err -22)

iwlwifi: Unknown symbol ieee80211_get_tkip_p1k_iv (err 0)

lsmod provides the following output:

mac80211 177127 0 - Live 0xbf037000

cfg80211 146105 1 mac80211, Live 0xbf004000

compat 1722 0 - Live 0xbf000000

From my development machine, modinfo on each of the drivers in output/.../system/lib/modules (including iwlwifi) gives me:

vermagic: 3.0.35-svn217 preempt mod_unload modversions ARMv7

I'm stumped at this point. My desire for getting this to work is to support the Intel N105 PCI-e module which is a replacement for the N100 that has gone EOL. Thank you.

It looks like I was copying the driver files from kernel_imx instead of compat-wireless per what was specified in my imx6.mk PRODUCT_COPY_FILES command. Although everything had the same modinfo, the ieee80211 routines had different magic values between the two versions and thus the error you see referenced above this message.
