Here you will read this None value (probably as string), because you initialized it as default in ansible code.

I'd better used something like:
default(0)
and in the test I'd use
if self.pkt_tx_count == 0:
self.pkt_tx_count = PKT_TX_COUNT

I don't know better way to omit pkt_tx_count from ptf_test_params in Ansible.
Probably
{% if pkt_tx_count is defined %} - pkt_tx_count={{ pkt_tx_count }} {% endif %}
will work but I didn't check it

ptf_extra_options: --device-socket 0-3@tcp://127.0.0.1:10900 --device-socket 1-3@tcp://{{ ansible_eth0['ipv4']['address'] }}:10900
