Table 6-2 shows a few use case scenarios and the examples as how to set the packet filter:

Note: Notes about the iw command:
  • The ”:-:” indicate a wild card byte which isn't matched
  • phy0 identifies the physical device. Best would be to verify what it is by using “iw list | grep wiphy

More on iw commands at https://wireless.wiki.kernel.org/en/users/documentation/iw.

Note: You should configure all unicast patterns in order to receive traffic intended for you. For more specific patterns, it is important to include a pattern to capture EAPOLs as these are used for AP Group Rekey, which occurs periodically. If these are missed, then after a re-key event the station will not be able to receive multicast and broadcast traffic as it would not have the right key to decrypt it (all of this is relevant only to WPA2 where there's re-key).
