it looks like it does work - it just takes a REAL long time to load with
"many" entries in the file.
iptables was never slow. firewalld seems inefficient.

I was able to add the line - restart the firewall, (wait) - see my packets
dropped - remove the line -
restart the firewall (wait) and able to ping again.

I thought this "Direct.xml" file would be the fastest way for firewalld -
but there is multi-minute wait to restart. I have about 14000 entries.
