└─>IPv4/IPV6 bridge connection tracking support
In linux kernel since version 5.1 (release Date: 2019-05-05)  
Connection tracking keeps a record of what packets have passed
through your machine, in order to figure out how they are related
into connections. This is used to enhance packet filtering via
stateful policies. Enable this if you want native tracking from
the bridge. This provides a replacement for the `br_netfilter'

To compile it as a module, choose M here. If unsure, say N.
