* 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.

iwlwifi: use iwl_hwrate_get_mac80211_idx where appropriate
For HT packets, mac80211 expects the rate_idx to be an MCS number, which is the
lower byte of rate_n_flags. However, iwl_hwrate_to_plcp_idx takes the MCS
number and reduces it down to the range 0-8 (6 to 60 Mbps), removing the bits
that signify multiply streams, HT40 Duplicate mode, or unequal modulation.
This version is used for various internal purposes through the driver.
Add the function iwl_hwrate_get_mac80211_idx, an alternate version which takes
the rate and the band and returns the mac80211 index (MCS, for HT packets, and
PLCP rate, for legacy packets).
