Thanks Michael, I knew there would have to be a way :) Here's a slightly
modified (and tested) version of your suggestion that might help someone
one day:
- hosts: all
tasks:
- name: assume no bnx2 modules
set_fact: bnx2=no
- name: flag we have a bnx2 module if we find any
set_fact: bnx2=yes
when: "'module' in hostvars[inventory_hostname]['ansible_' + item]
and hostvars[inventory_hostname]['ansible_' + item]['module'] == 'bnx2'"
with_items: ansible_interfaces
- name: bnx2 found
debug: msg="got one!"
when: bnx2 == 'yes'
