Subject: [PATCH] {nl,mac}80211: allow 4addr AP operation on crypto controlled
devices

-the device which has to advertise the support for AP/VLAN iftype
-based on it's capability to tranmsit packets encrypted in software
+As per the current design, in the case of sw crypto controlled devices,

(In VLAN functionality, group traffic generated for a specific
VLAN group is always encrypted in software). Commit db3bdcb9c3ff
("mac80211: allow AP_VLAN operation on crypto controlled devices")
@@ -16,25 +16,25 @@ Since 4addr AP operation also uses AP/VLAN iftype, this conditional
way of advertising AP/VLAN support has broken 4addr AP mode operation on
crypto controlled devices which do not support VLAN functionality.
-For example:
In the case of ath10k driver, not all firmwares have support for VLAN
functionality but all can support 4addr AP operation. Because AP/VLAN
support is not advertised for these devices, 4addr AP operations are
also blocked.
-Fix this by allowing 4addr opertion on devices which do not advertise
-AP/VLAN iftype but which can support 4addr operation (the desicion is
-taken based on the wiphy flag WIPHY_FLAG_4ADDR_AP).
+Fix this by allowing 4addr operation on devices which do not support
+AP/VLAN iftype but can support 4addr AP operation (decision is based on
+the wiphy flag WIPHY_FLAG_4ADDR_AP).
