wifi: iwlwifi: mvm: Offload RLC/SMPS functionality to firmware
Currently, the driver handles SMPS decisions by tracking AP
capabilities, BT coexistence changes, sending necessary SMPS
frames to the AP, and updating firmware with RX chain info
using the RLC_CONFIG_CMD.
Starting with version 3 of the RLC_CONFIG_CMD, the firmware
takes over this responsibility. It now tracks SMPS, sends
frames, and configures the RLC.
In this patch:
1. Stop sending RLC_CONFIG_CMD when firmware supports RLC
offload (version 3), as rlc.rx_chain_info is not needed by
firmware, and no other field in the cmd is used.
2. Prevent the driver from forwarding any SMPS requests to
mac80211, i.e., the driver should not transmit SMPS frames
to the AP as firmware handles that.
3. Set NL80211_FEATURE_DYNAMIC_SMPS and NL80211_FEATURE_STATIC_SMPS
conditionally based on RLC version.
