Hi Nathan,

The issue is gone after your patch is applied. Thanks for the fix. In the 
meantime, there is actually a compile warning which can be fixed by the 
following change:

Not sure if it makes sense for you to incorporate the change into your patch.

Hi Xiaodong,

It seems like a '.runs_after' was introduced on a node that does not belong to 
the arc in question. [0] should solve this.

Hi VPP experts,

I got the following error message when starting vpp recently:

0: vnet_feature_arc_init:272: feature node 'ip6-lookup' not found (before 'pt', 
arc 'ip6-output')

I'm using master branch from VPP git repo. By checking the source code, it 
seems it might have something to do with the comment 
https://github.com/FDio/vpp/commit/b79d09bbfa93f0f752f7249ad27a08eae0863a6b and 
https://github.com/FDio/vpp/commit/39d6deca5f71ee4fe772c10d76ed5b65d1ebec44
So I remove the two commits from my local repo and the issue is gone.

The message seems to be harmless, but if anyone who is familiar with the 
commits can take a look, I'd appreciate it.

Regards,
Xiaodong
