Neale,

 

I updated the code catering to your comments.  

 

https://gerrit.fd.io/r/c/vpp/+/32018

 

Also, at the end of the link below, there is a "key" mentioned.  This is the
key I am trying to support, but if an API already exists to serve such a
key, I'd like to know and cancel my code changes.

pentries.html

 

I have tested the changes with my private VPP plugin.

 

Thanks,

 

Hemant

Please don't change the semantics of existing APIs. Add a ip_neighbor_find
API if you need one. 

But what is it you are trying to do? Why are you searching the neighbour
table and in what context; main or worker thread?

In vpp/src/vnet/ip-neighbor/ip_neighbor.api, I don't see any API to find the
ip-neighbor entry to serve the purpose below.  So, first the doc at the link
below should change because the API does not exist.

Second, I changed, ip_neighbor_get_mac() as follows and now I have an API to
help me get the next-hop mac-address if I have the next-hop IP address and
link-type.  

 

Unless, I missed something, should we consider the code changes below?

Subject: [vpp-dev] dst mac-address look up?

 

I read this link:
https://fdio-vpp.readthedocs.io/en/latest/gettingstarted/developers/fib20/ar
pentries.html

 

At the end of the page, I see text that says "key for which is {interface,
next-hop, link-type}."

 

I have the data for the above key, but what API do I use to find destination
mac-address?
