[Hampus Thorell]

How do I use the stack from the EDK8.2i release specifically?

I'm using polled mode with a pretty small stack due to very little 
memory (only on-chip memory).

My stack configuration looks like this:
pbuf_link_len           16
pbuf_pool_bufsize       1536
pbuf_pool_size          64

Regards,
Hampus
