+Subject: [PATCH] cfg80211: Update Transition Disable policy during port
+ authorization
+
+In case of 4way handshake offload, transition disable policy
+updated by the AP during EAPOL 3/4 is not updated to the upper layer.
+This results in mismatch between transition disable policy
+between the upper layer and the driver. This patch addresses this
+issue by updating transition disable policy as part of port
+authorization indication.

+- Move ieee80211_valid_disable_subchannel_bitmap() from mlme.c to
+ chan.c, rename it as cfg80211_valid_disable_subchannel_bitmap()
+ and export it.
+- Modify the prototype to include struct cfg80211_chan_def instead
+ of only bandwidth to support a check which returns false if the
+ primary channel is punctured.

+Subject: [PATCH] wifi: nl80211: validate and configure puncturing bitmap
+
+- New feature flag, NL80211_EXT_FEATURE_PUNCT, to advertise
+ driver support for preamble puncturing in AP mode.
+- New attribute, NL80211_ATTR_PUNCT_BITMAP, to receive a puncturing
+ bitmap from the userspace during AP bring up (NL80211_CMD_START_AP)
+ and channel switch (NL80211_CMD_CHANNEL_SWITCH) operations. Each bit
+ corresponds to a 20 MHz channel in the operating bandwidth, lowest
+ bit for the lowest channel. Bit set to 1 indicates that the channel
+ is punctured. Higher 16 bits are reserved.
+- New members added to structures cfg80211_ap_settings and
+ cfg80211_csa_settings to propagate the bitmap to the driver after
+ validation.

+Subject: [PATCH] wifi: mac80211: add EHT MU-MIMO related flags in
+ ieee80211_bss_conf
+
+Similar to VHT/HE. This is utilized to pass MU-MIMO configurations
+from user space (i.e. hostapd) to driver.
