Macfilter on MT300N-V2


I have a MT300N-V2 with 2.2.64 firmware. Could anyone give me a hint how to setup a macfilter list for the wifi access point?

There is no macfilter option under Lede -> Network -> Wireless -> Edit [Master Wifi Device] -> Interface Configuration -> Wireless Security. I guess it should be there… neither it is in the tab “Interface Configuration -> General Setup”

Is there no support for macfilter only in 2.264 firmware or is it missing at all for the MT7628 chip that is used in MT300N-V2?

No one any idea?
