QoS: make tc filters match all traffic

Browse Source 
Up until now the traffic control filters for the vNIC QoS were
matching only ip traffic. For egress traffic that was unnoticed
because the unmatched traffic would just go to the default htb class
and be shaped anyway. For ingress, though, since the policing of the
rate is done by the filter itself.

The problem is solved by changing protocol to all and making anything
match the filter.
