The module is from Murata, will magic packet wakeup work with those?

I attached two pcap files. I'm using a router with openwrt flashed to it.

[magic packet]
I issue the command on the router, and check on the target that the
packet arrives:

router# etherwake -i wlan1 5C:F8:A1:15:1B:0B
target# tcpdump  -i wlan0  -w magic-packet.pcap

After seeing that magic packet arrive, I send the target
to sleep and send the magic-packet again

[ssh-packet-while sleep]
I open up an ssh session from host via router to the the target.
I sniff on the router for outgoing packets to target

host# ssh root@target
target# iw phy0 wowlan enable patterns 44+16
target# echo mem > /sys/power/state
router# tcpdump -i wlan1 dst 192.168.11.219 -w ssh-pkt-while-sleeping.pcap
