[c-nsp] QoS on LNS virtual-template

[Reuben Farrelly]

Hi,

What version of code are you running?

I have found 12.4 mainline worked ok, but somewhere along the 12.4T series and 
including 15.0(M) I cannot apply any QoS policies to Virtual-Access interfaces 
- policies just don't apply.  I have a TAC case open for this now...
