Pattern match is an option of WoWLAN to allow the device to be woken up
from suspend mode when receiving packets matched user-designed patterns.

The patterns are written into hardware via WoWLAN firmware in suspend
flow if users have set up them. If packets matched designed pattern are
received, WoWLAN firmware will send an interrupt and then wake up the
device.
