Subject[PATCH 3.16.y-ckt 066/183] iwlwifi: mvm: always use mac color zero
Date
3.16.7-ckt8 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Luciano Coelho <luciano.coelho@intel.com>

commit 5523d11cc46393a1e61b7ef4a0b2d4e7ed9521e4 upstream.

We don't really need to use different mac colors when adding mac
contexts, because they're not used anywhere. In fact, the firmware
doesn't accept 255 as a valid color, so we get into a SYSASSERT 0x3401
when we reach that.

Remove the color increment to use always zero and avoid reaching 255.
