Public bug reported:
Description of problem: The mlx5 Ethernet driver doesn't allow packets
marked with all possible VLAN tags to be accepted under promiscuous
mode. This is wrong and disallows Open-Stack to properly function in
Para-Virtual configuration.
How reproducible:
just put the NIC to promiscuous mode and send packet from another node
tagged any vlan which was not previously configured on the NIC vlan
filter, it will not be accepted.
Actual results:
ARP packets sent on vlan 52 packets are dropped
Expected results:
packets should received

net/mlx5e: Disable VLAN filter in promiscuous mode
When the device was set to promiscuous mode, we didn't disable
VLAN filtering, which is wrong behaviour, fix that.
Now when the device is set to promiscuous mode RX packets
sent over any VLAN (or no VLAN tag at all) will be accepted.

I backported it to Ubuntu 15.10 (please see the attached patch). This
issue need to be fix also in Ubuntu 14.04.4 not only 15.10.
