File /etc/modules being ignored on Xenial

[Martinx - ジェームズ]

Guys,

 I have a "/etc/modules" that contains:

---
br_netfilter
dummy numdummies=6
---

 However, after reboot, there is no dummy interfaces available!

 I can see that there is a link to "/etc/modules", here:

---
root at xenial-1:~# file /etc/modules-load.d/modules.conf
/etc/modules-load.d/modules.conf: symbolic link to ../modules
---

 But it is not working...

 Am I missing something?

Thanks!
Thiago
