Abhijeet Kolekar 37dc70fea8 iwlwifi/iwl3945: unify rts_tx_cmd_flag 
3945 and 4965 share the functionality for setting RTS and CTS to
the tx_cmd. Unify these functions and move the common
functionality to core.

* struct iwl_cfg
* @fw_name_pre: Firmware filename prefix. The api version and extension
* (.ucode) will be added to filename before loading from disk. The
* filename is constructed as fw_name_pre<api>.ucode.
* @ucode_api_max: Highest version of uCode API supported by driver.
* @ucode_api_min: Lowest version of uCode API supported by driver.
* @pa_type: used by 6000 series only to identify the type of Power Amplifier
* @max_ll_items: max number of OTP blocks
* @shadow_ram_support: shadow support for OTP memory
* @led_compensation: compensate on the led on/off time per HW according
* to the deviation to achieve the desired led frequency.
* The detail algorithm is described in iwl-led.c
* @use_rts_for_ht: use rts/cts protection for HT traffic
* @chain_noise_num_beacons: number of beacons used to compute chain noise
*
* We enable the driver to be backward compatible wrt API version. The
* driver specifies which APIs it supports (with @ucode_api_max being the
* highest and @ucode_api_min the lowest). Firmware will only be loaded if
* it has a supported API version. The firmware's API version will be
* stored in @iwl_priv, enabling the driver to make runtime changes based
* on firmware version used.
*
* For example,
* if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
* Driver interacts with Firmware API version >= 2.
* } else {
* Driver interacts with Firmware API version 1.
* }
*
* The ideal usage of this infrastructure is to treat a new ucode API
* release as a new hardware revision. That is, through utilizing the
* iwl_hcmd_utils_ops etc. we accommodate different command structures
* and flows between hardware versions (4965/5000) as well as their API
* versions.
