[c-nsp] Portchan ASR->2960

[John Elliot]

Ok - Found a "solution" to this....seems the ASR requires 

port-channel load-balance vlan-manual

Unusual  :)  
Is there any other gotchas's  that I should know about?

> Hi Guys,
> Testing an ASR1006->2960 portchan, and portchan comes up, config vlan int on 2960 in vlan 88 and portchan1.88 and can see mac's but cannot pass data - If I change the config to bring down the portchan, and use physical interface on asr with dot1q subint, I have no issues?  Bug?
