I can confirm this also happens with a 7260 on 13.1-RC2. I can NOT
get it to work on warm or cold boot. I use devmatch_blacklist="if_iwm.ko"
However. After login, if I send a
service netif restart
everything works as intended. I know this is a 7260 and not 8265 / 9560.
But thought it still might be useful to know.
