Packet type which is required by firmware is determined based on provided patterns in a rule: Unicast: if pattern '01' with offset 0 is found Multicast: if pattern '33:33' or '01:00:5e' with offset 0 is found Broadcast: if pattern 'ff:ff:ff:ff' with offset 0 is found Some example coalesce configuration files: 1) Coalesce Rx data packets from 192.168.0.88 mac address of our device is 00:50:43:21:53:7A Source IP address offset comes out as 52 after following calculations: 32 bytes of HW 802.11 header + 8 bytes LLC + 12 bytes in IPV4 header till source IP address Destination mac is at offset 6 in HW header. delay=100 condition=1 patterns=01,6+00:50:43:22,10+53:7A,52+c0:a8:00:58 2) Coalesce all broadcast and multicast packets(Multiple packet types are not allowed in a single rule. Hence created separate rules) delay=400 condition=1 patterns=33:33 delay=400 condition=1 patterns=ff:ff:ff:ff Signed-off-by: Amitkumar Karwar Signed-off-by: Bing Zhao Signed-off-by: John W.
