ESP-WIFI-MESH : How to increase priorities of multicast packets?

[kponnus]

Hi,
I am working on a product where we use esp wifi mesh. The parent node connects to multiple child nodes and streams data continously over multicast. The data rate is very less(less than 1 megabits per second).

How to improve the data rate over multicast?
How to give high priority to multicast packet?

Note: With the unicast solution , the data rate is around 6 megabits per second.

Thanks,
Karthick
