[PATCH RESEND 3.9 0/4] Enable 7000 device family on 3.9

[PATCH RESEND 3.9 0/4] Enable 7000 device family on 3.9

[Emmanuel Grumbach]

This small patch series enables 7260 and 3160 devices on 3.9
kernel. Three patches are already in linux.git (3.11-rc1).
One patch is 3.9 specific and disables configuration that is not
supported in 3.9.

Dor Shaish (1):
  iwlwifi: mvm: don't use cts to self

Emmanuel Grumbach (1):
  iwlwifi: mvm: support BSS only

Johannes Berg (2):
  iwlwifi: mvm: adjust firmware D3 configuration API
  iwlwifi: bump required firmware API version for 3160/7260

[PATCH RESEND 3.9 1/4] iwlwifi: mvm: don't use cts to self

[Emmanuel Grumbach]

From: Dor Shaish <dor.shaish@intel.com>

commit cc7ee2bab3d90b0a09651dcfa2d0c9ec1a115bc8  upstream.

The current fw doesn't currently support cts to self. There
is a bug in the fw that prevents us from using cts to self.
Use full protection (including RTS) for now.

[PATCH RESEND 3.9 2/4] iwlwifi: mvm: support BSS only

[Emmanuel Grumbach]

Only BSS is support in 3.9. In later kernels, other modes
have been fixed and tested to work.
This will at least allow user to use the regular wifi
functionality.

[PATCH RESEND 3.9 3/4] iwlwifi: mvm: adjust firmware D3 configuration API

[Emmanuel Grumbach]

From: Johannes Berg <johannes.berg@intel.com>

commit dfcb4c3aacedee6838e436fb575b31e138505203 upstream.

The D3 firmware API changed to include a new field, adjust
the driver to it to avoid getting an NMI when configuring.

[PATCH RESEND 3.9 4/4] iwlwifi: bump required firmware API version for 3160/7260

[Emmanuel Grumbach]

From: Johannes Berg <johannes.berg@intel.com>

commit a2d0909a687b4d250cc2b7481072e361678745ba upstream.

As the firmware API has changed significantly and we don't
have support code for the old APIs, bump the version to be
able to release the version 7 API firmware.
