Cool. Next time you have time, please go ahead and make the change. 

 

I’m planning to use the L2 classify path in a use-case which would never be 
enabled at the same time as the ACL plugin, so no drama expected. (😉)...

Dear Dave,

 

ACL plugin is using l2 classify path for traffic diversion and also dispatching 
the dot1q/dot1ad packets to the correct ip4/ip6 acl plugin node by matching on 
the inner ethertype...

 

I could probably make use of this change to push some more intelligence of the 
stateless traffic matching to classifier as an acceleration measure for some 
specific cases.. (assuming the idea is to do it uniformly for input&output 
paths)..

Dear John,

 

I’m wondering about copying e0->metadata into vlib_buffer (b)->l2_classify.xxx 
in l2_input_classify. On the face of it, that seems reasonable. Do you see 
obvious problems with that idea?

 

Related question, for vpp-dev: is anyone using L2 input or output 
classification these days? If so, will this change help, hurt, or do nothing in 
your use case?

 

Thanks... Dave
