Subject: [PATCH] nl80211: report 4ADDR status with GET_INTERFACE
Git-commit: 446faa15c6e80620826edd659e63c6760137975a
Patch-mainline: v4.19-rc1
References: FATE#326294
User space tools might be interested in knowing the current
status of the 4ADDR property of an interface (when supported).
Send the status along with the other attributes when replying
to a GET_INTERFACE netlink query.
