Enable iwlwifi drivers for compat-wireless v3.2 backports

[Leann Ogasawara]

=== SRU Justification ===
Per bug 918351 we provided the v3.2 compat-wireless stack via LBM for Oneiric. Unfortunately the iwlwifi drivers were not enabled. This is due to the fact that in v3.2 iwlagn was renamed to iwlwifi and the corresponding config names were also updated to reflect this re-name, ie:

    iwlagn: rename iwlagn module iwlwifi and alias to iwlagn.

    Rename the iwlagn module as iwlwifi in preparation for future
    changes. Add an alias to iwlagn for backward compatibility.

As a result, the v3.2 compat-wirless stack enables iwlwifi if CONFIG_IWLWIFI. However, because CONFIG_IWLWIFI does not exist for Oneiric, the v3.2 compat-wireless version of iwlwifi was/is never built.

obj-$(CONFIG_IWLWIFI) += iwlwifi.o
etc...

== Fix ==
Modify the v3.2 compat-wireless makefile to check be dependent on CONFIG_IWLAGN instead of CONFIG_IWLWIFI. See attached patch.

==Test Case==
Install linux-backports-modules-3.0.0 for Oneiric and confirm that without the patch applied updated cw-3.2 iwlwifi drivers are unavailable. With the patch applied, they are available.

I've built a test LBM package for Oneiric with the patch from comment #1 applied. It can be found at the following location. Please note that you'll need to be running the linux-3.0.0-16 kernel from oneiric-proposed in order to install this test package.

This is also now an Oneiric LBM test package for i386 at:

http://people.canonical.com/~ogasawara/lp923900/i386/

Note, that I provided both the -generic and -generic-pae flavors.

I can confirm that on Oneiric with -16 kernel from proposed, this compat wireless modules fixed wifi on Centrino N 2200 wifi card.

This bug was fixed in the package linux-backports-modules-3.0.0 - 3.0.0-16.9
