2013-12-09iwlwifi: mvm: don't configure mimo rates if nss is limited to 1Eyal Shapira
Remote peer can publish a different number of supported nss via the operating mode notification IE or action frame. If it limits to 1 then we don't want mimo rates configured in the rate table.

2013-12-09iwlwifi: mvm: don't enable VHT MCS9 in 20MhzEyal Shapira
MCS9 in NSS=1 or NSS=2 isn't valid for 20Mhz so don't enable it in case we're dealing with a 20Mhz sta. Trying to configure an MCS9 rate with 20Mhz in the LQ rate table would lead to a FW assert.

2013-12-09iwlwifi: mvm: stop using MIMO in case BT doesn't allow itEyal Shapira
Switch to using the new btcoex decision api regarding MIMO and stop accessing the internal btcoex structs. In case MIMO should be disabled it would detect this upon the next Tx and force a search. The search will switch to SISO on a antenna A which isn't used by BT. Signed-off-by: Eyal Shapira <eyal@wizery.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
