Add two new parameters to iwl_cfg: max_ht_ampdu_exponent and max_vht_ampdu_exponent. These parameters, if set, will set new values to the maximum of HT and VHT A-MPDU exponent for the A-MPDU length exponent.

2014-02-23iwlwifi: nvm: remove reading valid antennas from NVMJohannes Berg
These values aren't used as the firmware values should be used, so reading them is pointless and hides potential errors when somebody uses these values. Leave them zero to make it clearer that they can't be used. We can't remove the struct members as the DVM driver does read the values from EEPROM/OTP and the structure is shared between drivers.

2014-02-02iwlwifi: mvm: don't allow A band if SKU forbids itEmmanuel Grumbach
The driver wasn't reading the NVM properly. While this didn't lead to any issue until now, it seems that there is an old version of the NVM in the wild. In this version, the A band channels appear to be valid but the SKU capabilities (another field of the NVM) says that A band isn't supported at all. With this specific version of the NVM, the driver would think that A band is supported while the HW / firmware don't. This leads to asserts.

Keeping this as 0 is ok according to spec section 9.7.11 as this means the limits are according to the Tx/Rx supported MCS x NSS bitmap.

These two flags are used for the same purpose, just combine them into a no-ir flag to annotate no initiating radiation is allowed. Old userspace sending either flag will have it treated as the no-ir flag. To be considerate to older userspace we also send both the no-ir flag and the old no-ibss flags.
