wifi: iwlwifi: mvm: support set_antenna() set_antenna() is supported only when the device is not started in mac80211 which translates to the firmware not being loaded in iwlwifi. The tricky part is that iwlwifi populates the sband data during its boot and doesn't touch this data afterwards, but if the antenna settings forbid MIMO, we need to update the sband data. Rework the nvm parsing code to allow to get an existing nvm_data and modify the sband with additional constraints (tx / rx chains masks).

iwlwifi: separate elements from cfg that are needed by trans_alloc In order to be able to select the cfg depending on the HW revision or on the RF ID, we need to set up the trans before selecting the cfg. To do so, move the elements from cfg that are needed by iwl_trans_alloc() to a separate struct at the top of the cfg, so it can be used by other cfg types as well, before selecting the rest of the configuration.

iwlwifi: eeprom-parse: use struct_size() in kzalloc() One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

iwlwifi: move iwl_nvm_check_version() into dvm This function is only half-used by mvm (i.e. only the nvm_version part matters, since the calibration version is irrelevant), so it's pointless to export it from iwlwifi. If mvm uses this function, it has the additional complexity of setting the calib version to a bogus value on all cfg structs. To avoid this, move the function to dvm and make a simple comparison of the nvm_version in mvm instead. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

iwlwifi: advertise maximal MPDU length when Rx MQ is supported The new hardware that supports multiple queue also de-aggregates A-MSDUs. This means that we can advertise the maximal size of A-MSDUs regardless of the receive buffer's size. In order to be able to forcefully use a lower A-MSDU size, add a default value for the module parameter. Pre-9000 will have a default of 4K, and 9000 will have 12K. Setting the amsdu_size module parameter to 4K will limit the A-MSDU on 9000 as well.

iwlwifi: add support for 12K Receive Buffers 802.11ac allows A-MSDU that can be up to 12KB long. Since an entire A-MSDU needs to fit into one single Receive Buffer (RB), add support for big RBs. Since this adds lots of pressure to the memory manager and significantly increase the true_size of the RX buffers, don't enable this by default.
