Sorry, 2 issues testing this series:
1. ipv4 addresses seem broken, or maybe i'm using them wrong.
Client command:
yes $(echo -e \\x01\\x02\\x03\\x04\\x05\\x06) | tr \\n \\0 | head -c

./ncdevmem: Failed to configure flow steering
The ethtool command to configure flow steering is not working for me.
It thinks it's in v6 mode, when the ip address is a v4 address.
(notice `-s 192.168.1.4 -c 192.168.1.5`). flow-type should be tcp in
this case.
