In-port in wireless (wifi) network

[hamzehmohammadnia]

Hi,

As far as I know, in wired network when a packet is received we can easily fetch in_port (ofp_match.in_port) and also based on matching policy/plan set the out_port. Im wondering how it should be implemented in wifi network since access point has no specific port per each connected mobile station? Is it there already any implemented solution to address out_port and in_port to manage security strategies?
Best,
